When it comes to macrame jewelry, cord size makes or breaks the finished piece. The best cord for macrame jewelry is either 1.5mm or 2mm single-strand cotton cord — fine enough to knot comfortably, yet sturdy enough to hold its shape when worn. Understanding the practical differences between these two sizes will help you choose the right one for bracelets, earrings, anklets, and other wearable pieces.

Why Thin Cord Is Essential for Jewelry
Standard macrame projects use 3mm, 4mm, or 5mm cord. For wall hangings and plant hangers, that thickness creates the bold texture and weight those pieces need. But jewelry lives on the body — close to skin, worn all day, expected to feel comfortable and look refined.
At 3mm and above, knots become chunky and stiff. A square knot in 4mm cord produces a bead roughly the size of a small marble. Fine for a wall hanging detail; uncomfortably bulky on a wrist. Dropping down to 1.5mm or 2mm cord produces knots that are small, tight, and elegant — proportional to jewelry scale.
If you are new to macrame in general, the beginner’s guide to macrame covers the foundational knots you will use across all project types, including jewelry.
1.5mm vs 2mm Cord: The Core Differences
Knot Definition
Both sizes produce well-defined knots when tied with consistent tension, but they behave slightly differently.
1.5mm cord creates very fine, compact knots. Square knots tied in 1.5mm cord are roughly the size of a small bead — ideal for intricate patterns and delicate layered bracelets. The knots read crisply, especially in natural or solid colors.
2mm cord produces a noticeably fuller knot. The extra half-millimeter translates to knots that feel more substantial and are easier to see from a distance. For beginners, 2mm is more forgiving: the knots are easier to manipulate, and small tension inconsistencies are less visible than they would be in 1.5mm.
For your first jewelry project, 2mm is the easier starting point. Move to 1.5mm once you have consistent tension down.
Drape and Flexibility
Cord drape describes how the cord falls and moves — this matters enormously for bracelets, which need to flex around the wrist without feeling stiff.
1.5mm cord has excellent drape. A knotted section in 1.5mm feels almost fabric-like, conforming naturally to the curve of a wrist. This makes it ideal for wide cuff bracelets and anklets where the piece needs to wrap smoothly.
2mm cord has slightly less drape — not stiff, but with a bit more body. For simpler knotted bracelets (a single row of square knots, for example), 2mm holds its shape attractively. For more complex multi-strand woven designs, 1.5mm moves more naturally.
Colorfast Properties
Both the 1.5mm Macrame String (100m) and 2mm Single-Strand Macrame Cord (100m) from Bochiknot are available in natural undyed cotton and a range of dyed colors. For jewelry that contacts skin directly, colorfastness is worth paying attention to.
Natural, undyed cord is the safest choice for anyone with sensitive skin. If you want color in your jewelry:
- Look for cords labeled “colorfast” or “dye-stable”
- Test a small piece of dyed cord by rubbing it with a damp white cloth — if color transfers, it may bleed against skin
- Pre-soaking a small length before knotting can help set loose dye
In practice, quality cotton cords from reputable suppliers hold their color well. The risk is higher with very bright or deeply saturated colors, where more dye is present in the fiber.
Skin Safety Considerations
For pieces worn directly against skin, the cord material matters as much as the size.
Natural cotton (which both these cords are) is the best choice for jewelry. It is soft, breathable, and rarely irritating. Synthetic cords — nylon, polyester, or mixed blends — can cause friction or discomfort during long wear, particularly at knotted sections where the cord sits against the wrist or neck.
Avoid cords treated with stiffening agents or chemical finishes. These are sometimes used on cords marketed for outdoor projects or structural work, and they can cause skin reactions with prolonged contact.
Both the 1.5mm and 2mm single-strand cotton options are appropriate for skin contact. Use code KNOT10 for 10% off either size.
Which Cord to Buy First
| Use Case | Recommended Size |
|---|---|
| Delicate bracelets and earrings | 1.5mm |
| First jewelry project | 2mm |
| Multi-strand woven cuffs | 1.5mm |
| Simple knotted friendship bracelets | 2mm |
| Macrame earrings with fine detail | 1.5mm |
| Anklets and chokers | 1.5mm or 2mm |
If you can only buy one size to start, go with 2mm. The knots are easier to tie and see, mistakes are easier to correct, and you can still make beautiful, wearable pieces. Once you are comfortable with tension and pattern reading, add 1.5mm to your kit for more refined work.
Working with Thin Cord: Practical Tips
Thin cord behaves differently from the 4mm cord used in most macrame tutorials. A few adjustments will save you frustration.
Cut generously. With 1.5mm and 2mm cord, it is tempting to cut shorter lengths since the cord is finer — but thin cord travels through knots quickly. For a bracelet, plan on working cords 8 to 10 times the finished length. A 7-inch bracelet needs working cords around 60 to 70 inches long.
Use a knotting board. A macrame board with T-pins helps enormously with jewelry work. Pinning the work down frees both hands for manipulating the cord, which makes a significant difference with thin cord where small movements affect tension. The Macrame Board with T-Pins is a worthwhile investment for regular jewelry making.
Invest in precision scissors. Trimming ends close to knots in fine jewelry requires small, sharp blades. The 5“ Gold Precision Macrame Scissors is specifically designed for this kind of close, controlled trimming — the short blade gives you visibility and control that a larger pair does not.
Work in good light. Thin cord in natural or light colors can be hard to track visually, especially when multiple cords cross. Good lighting — or a contrasting dark work surface under light cord — helps you see what you are doing.
Manage your cord length. Long working cords tangle easily with thin cord. Bundle them with a simple overhand loop or a small clip, and unroll as you knot rather than working with the full length hanging free.
Cord for Specific Jewelry Types
Bracelets
Both 1.5mm and 2mm work for bracelets. For a simple spiral or square knot bracelet, 2mm produces a clean result and is easier for first attempts. For wider cuffs or more intricate patterns like the Josephine knot, 1.5mm gives you finer results.
Earrings
For macrame earrings, 1.5mm is generally the better choice. Earrings need to be lightweight, and 2mm cord adds noticeable weight over a full pair. The finer cord also allows for more intricate knotwork within the small scale of an earring.
Anklets and Chokers
For pieces worn around ankles or necks, 1.5mm has the right drape to sit comfortably without feeling stiff or heavy. Use a softer natural cotton rather than a stiffer cord variant.
Macrame Knots That Work at Jewelry Scale
Not every macrame knot translates well to jewelry scale. These work particularly well in 1.5mm and 2mm cord:
- Square knots — the backbone of most bracelet patterns; reads crisply at fine scale
- Half hitch spirals — creates a twisted rope texture that looks very polished in thin cord
- Lark’s head knots — for attaching cord to a ring, chain, or clasp
- Overhand knots — for simple adjustable closures
- Berry knots — possible at 2mm with enough square knots stacked; creates subtle raised texture
For a refresher on the half hitch spiral that’s particularly popular in jewelry, see the spiral knot macrame tutorial.
