Material Categories and How to Match Them to Projects
Most jewelry designs become easier when you choose materials in this order: (1) the beads or focal components, (2) the structure material (wire or cord that holds shape), and (3) the stringing medium (what passes through bead holes). Your choices should reflect three practical constraints: wear (abrasion, sweat, movement), weight (comfort and sag), and flexibility (drape vs rigidity).
| Material category | Primary job | Typical decision factors |
|---|---|---|
| Beads | Look, weight, texture | Hole size, bead weight, edge sharpness, finish durability |
| Wire | Structure, loops, frames | Temper (dead-soft/half-hard), gauge, shape, metal type |
| Stringing materials | Connect beads, provide drape | Diameter, flexibility, abrasion resistance, stretch, knotting ability |
Beads: Types, Hole Sizes, and What They Mean for Stringing
Common bead materials and use cases
- Glass: Smooth holes (often), wide variety of sizes and finishes. Great for most stringing and wire-wrapping. Watch for heavy glass in long necklaces (can cause neck fatigue).
- Stone (gemstone): Heavier; holes can be narrower and sometimes slightly rough. Best on strong, abrasion-resistant stringing (beading wire or heavier thread). Consider weight for earrings.
- Metal beads: Add weight and can have sharper hole edges depending on manufacturing. Often used as spacers; pair with abrasion-resistant media and consider tarnish behavior.
- Plastic/acrylic: Lightweight, often larger holes. Good for statement pieces that must stay light (earrings, long necklaces). Can scratch; avoid high-friction stringing if the finish is delicate.
How hole size affects your stringing choice
Bead holes set the maximum diameter of what can pass through, including any doubled thread, knots, or crimp covers. Two beads of the same outer size can have very different hole sizes, so always test.
| Hole situation | What it implies | Common solutions |
|---|---|---|
| Very small holes (seed beads, some stones) | Limits diameter; friction is higher | Nylon thread, fine beading wire, or thin wire; consider fewer passes |
| Medium holes (many glass rounds) | Most media fit | Beading wire, nylon thread, thin leather, some elastics |
| Large holes (many plastic, large metal) | May look “gappy” on thin media | Thicker cord, multiple strands, or add smaller spacer beads |
Step-by-step: Test-fit bead holes before committing
- Pick a “sample set” of short offcuts: a piece of your intended beading wire, a piece of your intended thread (single and doubled), and a short piece of craft wire in a few gauges you commonly use.
- Dry-fit the bead: try passing the sample through the bead hole. If it catches, don’t force it—note whether the issue is diameter or roughness.
- Check for doubled passes: if your design needs two passes (common near clasps or when tying knots), test with two strands together.
- Assess hole smoothness: slide the bead back and forth on the sample. If you feel scraping, choose a more abrasion-resistant medium (beading wire over thread) or plan to use bead tips/guards where needed.
- Use a bead reamer only when appropriate: for stone or glass, gently ream with water as lubricant and minimal pressure. Ream just enough to fit; over-reaming weakens beads and can chip edges.
Wire: Temper, Gauge, Shape, and When to Use Each
Temper: dead-soft vs half-hard
Dead-soft wire bends easily and is ideal when you need tight wraps, coiling, or shaping around beads without spring-back. Half-hard wire holds shape better and is preferred for ear wires, simple frames, and components that must resist bending during wear.
| Temper | Best for | Limitations |
|---|---|---|
| Dead-soft | Wire-wrapping, coiling, weaving, intricate curves | Can deform more easily in finished pieces |
| Half-hard | Ear wires, simple bangles, structural links, frames | Harder to make tight wraps; more spring-back |
Gauge: choosing thickness for strength vs finesse
Gauge numbers work “backwards”: smaller number = thicker wire. Choose gauge based on the job the wire is doing.
- 18–20 gauge: sturdy loops, simple bangles, some clasps and frames (heavier look).
- 21–22 gauge: general-purpose for wrapped loops and links (balance of strength and ease).
- 24–26 gauge: wrapping wire for securing beads to a frame (not for load-bearing loops).
- 28 gauge and finer: weaving and delicate binding (decorative, not structural).
Wire shapes: round, square, half-round
- Round wire: most common; best for loops, jump rings, and general wrapping.
- Square wire: crisp edges and more “architectural” look; can be harder on bead holes and thread if used as a pass-through.
- Half-round wire: often used to bind bundles or frames (flat side sits neatly against a base wire).
Quick matching guide: wire use cases
| Task | Recommended wire | Why |
|---|---|---|
| Wrapped loop on a bead link | 20–22g dead-soft or half-hard (depending on stiffness needed) | Enough strength; workable for wraps |
| Ear wires | 20–21g half-hard | Resists bending during wear |
| Decorative wraps on a frame | 24–26g dead-soft | Wraps tightly without cracking or springing |
| Simple frame (teardrop, circle) | 18–20g half-hard | Holds shape and supports bead weight |
Stringing Materials: Strengths, Limitations, and Typical Applications
Beading wire (multi-strand coated cable)
Beading wire is a flexible steel cable with a nylon coating. It drapes well and resists abrasion, making it a go-to for bracelets and necklaces with heavier beads.

- Strengths: strong, kink-resistant (especially higher strand counts), good drape, handles sharp-ish bead edges better than thread.
- Limitations: cannot be knotted reliably for security; typically finished with crimps; can kink if bent sharply.
- Typical applications: gemstone strands, glass bead necklaces, charm-style bracelets (with appropriate finishing).
Nylon thread (for bead weaving and knotting)
Nylon thread is flexible and excellent for multiple passes through small holes and for techniques that rely on knots.
- Strengths: fits small holes, easy multiple passes, knots well, great for bead weaving.
- Limitations: can fray on rough holes; needs conditioning in some cases; less ideal for heavy beads without proper technique.
- Typical applications: seed bead projects, pearl-style knotting (with suitable thread), woven bracelets.
Elastic cord (stretch bracelets)
Elastic is chosen when you want a bracelet that slips on without a clasp. It must be matched carefully to bead weight and hole smoothness.
- Strengths: no clasp needed, comfortable fit, fast to assemble.
- Limitations: degrades with time, UV, and chemicals; can snap if abraded; knots must be secured and hidden.
- Typical applications: stretch bracelets with smooth-hole beads (many glass and some stone).
Leather cord (natural look, medium stiffness)
Leather cord adds body and a casual style. It works best with larger-hole beads or as a base for pendants and simple designs.
- Strengths: attractive texture, holds gentle curves, good for rustic styles.
- Limitations: thickness limits bead choices; can dry out; not ideal for repeated wet exposure; ends require appropriate findings.
- Typical applications: pendant necklaces, wrap bracelets, large-hole bead designs.
Reading Packaging Specs: What Matters and How to Interpret It
Wire packaging: diameter, gauge, temper, and shape
- Gauge: indicates thickness (e.g., 22g). Thicker wire is stronger but harder to manipulate.
- Diameter (mm): sometimes listed alongside gauge; useful when matching to bead holes precisely.
- Temper: dead-soft vs half-hard tells you how well it holds shape.
- Shape: round/square/half-round affects look and how it behaves in wraps and against bead holes.
Beading wire packaging: diameter and strand count
- Diameter: common sizes are around 0.010–0.024 in (or similar in mm). Thicker = stronger but may not fit small holes.
- Strand count: higher strand count generally means more flexibility and better kink resistance (e.g., 7-strand vs 49-strand). More strands usually drape better and feel smoother.
Thread and cord packaging: diameter and tensile strength
- Diameter: determines what fits through bead holes and whether you can do multiple passes.
- Tensile strength: the maximum pulling force before breaking. Use it as a baseline, then adjust for real-world wear (abrasion, knots, and sharp edges reduce effective strength).
Step-by-step: A quick “spec check” before you buy or cut
- Identify the smallest bead hole in your design (often spacers or gemstone rounds).
- Decide how many passes you need through that bead (one pass for simple stringing; two or more for weaving or reinforced ends).
- Match diameter first: pick a medium that fits with the required number of passes.
- Then match strength and drape: heavier beads and longer strands need stronger media with good abrasion resistance.
- Confirm finishing compatibility: beading wire pairs with crimps; elastic needs knot-hiding strategies; leather needs end caps or appropriate connectors.
Structured Comparison Activity: Choose the Best Material Set
Use the table below as a decision exercise. For each project, choose (A) bead type/weight, (B) structure material (wire vs cord), and (C) stringing medium. Base your choices on wear, weight, and flexibility.
| Project | Wear factors | Weight factors | Flexibility needs | Best material choice (example answer) |
|---|---|---|---|---|
| Bracelet (daily wear) | High abrasion on desk, frequent movement, occasional moisture | Moderate; should feel secure | Needs comfortable drape | Beads: smooth glass or well-drilled stone spacers Stringing: multi-strand beading wire (higher strand count) for abrasion resistance Why: strong, flexible, resists fraying better than thread for daily wear |
| Necklace (statement strand) | Lower abrasion than bracelet, but long-term rubbing at clasp area | Can become heavy quickly | Drape matters for comfort | Beads: lighter glass mix or limited stone focal sections Stringing: beading wire for weight support and drape, or nylon thread if doing multiple passes with small holes Why: supports weight while maintaining a smooth curve |
| Earrings (pair) | Movement, snag risk, skin contact | Must be light to avoid discomfort | Needs shape retention in findings | Beads: lightweight glass or small stones Structure: half-hard wire for ear wires and simple links Why: half-hard holds shape; lighter beads reduce pull on the ear |
Step-by-step: Do the activity with your own bead set
- Lay out your candidate beads and pick one “heaviest” option and one “lightest” option for each project.
- Measure or estimate hole constraints by test-fitting with your sample wire/thread pieces.
- Assign a wear rating (low/medium/high) based on where the piece will rub (bracelets are usually highest).
- Choose the medium: if wear is high or holes are rough, favor beading wire; if holes are tiny and you need multiple passes, favor nylon thread; if no clasp is desired, consider elastic with smooth-hole beads.
- Validate comfort: hold the laid-out strand against your wrist/neck/ear area to judge weight and drape before committing.
Storage Practices: Prevent Kinks, Tarnish, and Tangles
Preventing kinks (especially in beading wire)
- Store beading wire on its spool or in large, gentle coils; avoid tight bends.
- Don’t fold finished strands; hang necklaces or lay them flat in a long compartment.
- Separate heavy strands so they don’t press sharp angles into softer pieces.
Reducing tarnish on metal beads and wire
- Keep metals dry: store away from humidity (bathrooms are tough on finishes).
- Use anti-tarnish storage: anti-tarnish strips or bags in closed containers help slow oxidation.
- Separate reactive metals: store different metal types apart to reduce scratching and finish transfer.
Preventing tangles and surface scratches
- Use individual pouches or compartments for chains and finished necklaces.
- Keep bead strands from rubbing: glass and polished stone can scratch softer finishes; store with soft dividers.
- Label by diameter and type: keep cords and wires organized by size so you don’t repeatedly unspool and re-coil (a common cause of tangles and kinks).
