How To Choose The Right Elastic Cords For Jewelry Making

Choosing the right elastic stretchy cord is crucial to your jewelry's longevity, look, and feel. With many types of cords available, it can be challenging to know which one to choose for your jewelry-making applications.

At Tejas Beads, we receive a lot of questions about what size of elastic cord to use - the answer to this question is dependent hole size, but it's not as straightforward as it may seem at first glance.

This article aims to help answer some of the fundamental questions about elastic cord sizes and material types.

What Size Elastic Cord Should I Use?

Elastic stretchy cord comes in 0.5mm, 0.8mm, and 1.0mm sizes. When selecting an elastic cord, the general rule is to choose the largest cord that will fit in the bead holes without stressing the beads. A larger cord will result in stronger and longer-lasting jewelry with more sought after elastic spring.

The challenge of selecting an elastic cord is that all beads holes are not the same size because they are manufactured by different factories with different hole size standards. With that said, standard drill beads typically have holes ranging from 10% to 15% of the bead size.

Elastic Cord Sizing Chart

This image above shows what cords will fit different standard drill bead sizes. While the chart shows 3 sizes of Elasticity and only 1 size of Elastic Floss. However, 0.8mm and 1.0mm Elastic Floss also exist and can be used trial and error style to find the right combination of size and doubling for the beads you are working with.Β

Standard Elastic Cord vs Elastic Floss Cord

Standard elastic cords are firm rubber and do not squish much resulting in little flexibility when dealing with smaller holes. The one exception to this is the Elastic Floss material. Elastic Floss Cord tends to be slightly smaller than the stated diameter as it's not perfectly round, meaning that it has some lesser size dimensions. Floss is also very stretchy and super squishy, allowing 0.5mm diameter Elastic Floss to be doubled up and pulled through with a needle in even 4mm beads (and sometimes slightly smaller but it's a gamble). Elastic Floss is a strong material, and it is recommended for all bead sizes. With larger holes just run the cord through the beads as many times as the hole size allows without stressing the hole.

Threading Floss Through A Bead

The image above shows 8mm beads on 0.5mm Elastic Floss. Elastic Floss 0.5mm is the most versatile size that will work through the the entire range of bead sizes greater than 4mm.

Preparation and Tying

It's important to pre-stretch your elastic cord before working with it to prevent it from getting loose over time. Pre-stretching is less necessary when working with Elastic Floss, but it doesn't hurt.

It's helpful to stretch the cord slightly when tying. This will ensure that the final product feels firm and solid instead of flimsy and loose. And a dab of beading glue is recommended on the knot for good measure.

Final Thoughts

Standard elastic cord such as the Beadalon Elasticity is a long-time trusted choice. Elastic Floss on the other hand provides a different feel to your jewelry, is long-lasting, and is excellent for smaller hole sizes when it's getting a little tight. Remember that Floss has to be doubled at a minimum and threaded through with a beading needle.

Given how important it is to select the optimal cord, every experienced jewelry maker has many options on hand. If you plan to make a lot of jewelry, it is strongly recommended to get a wide array of Elastic Cords to ensure that you always have something that works in a pinch.
