Bead Weaving Warp Coil Cheat Sheet

Before you begin weaving on a Mirrix Loom, you need to choose the correct spring (also called a warp coil) to place on the top bar of the loom (or top and bottom if you are using a bottom spring kit).  

This spring sets the spacing of the warp threads on the loom. 

When choosing which spring to use for bead weaving, you want one that will set the spacing for the exact size of beads that you are using. 

You can figure out which spring to use by doing this: Place the beads you plan on weaving on a needle and measure an inch. Then, count how many beads are in that inch. The number of beads minus one is the warp coil that will be used. There is some leeway in this, and depending on the beads you are using, it might not work out perfectly (numerically), just close. Using a smaller (lower number) coil is better than using a larger (higher number) coil.

8/0- 9 per inch. Use the 8 dent spring

10/0- 14 per inch. Use 12 dent spring

11/0- 19 per inch. Use 18 dent spring except when doing very wide pieces, when you can use the 16 dent spring.

15/0- 25 per inch. Use the 22 dent coil just in order to space the beads. That is the largest coil we can make.

Seed Beads:

15/0- 24 per inch. Use 22 dent spring.

11/0- 14 to 15 per inch (size vary slightly depending on finish and manufacturer). Use 14 dent spring.

8/0-12 per inch. Use 10 or 12 dent spring depending on what size warp you are using. For example, when using the bead cord, because it is thicker, you will use the 10 dent spring. But if just weaving straight beads using beading thread as warp, you would use the 12 dent spring.

6/0-8 per inch. Use the 12 dent spring warped every-other-dent for 6 dents per inch.
