Bottom Spring Kit with One 18 Dent Coil and Two 16 Dent Coils
The Bottom Spring Kit is a plastic tray for holding a spring (warp coil) at the bottom of the loom (like the one at the top of most Mirrix looms) with two attached brass acorn nuts for holding the spring (warp coil).
The Bottom Spring Kit is useful for keeping warp threads correctly aligned when putting on the first row of beads or for evenly spacing the warp for tapestry weaving. It is simply and easily attached with permanent 2-sided tape.
Bottom Spring Kits are perfect for:
-Weaving wide bead pieces (especially with the shedding device)
-Weaving wide tapestry pieces
-Small format tapestry (more than 18 DPI)
This Bottom Spring Kit package is great for those who want to weave beads with 11/0 Delicas and has purchased or is purchasing a Mirrix with a shedding device that already comes with one 18 dent coil (as well as 8, 12 and 14, dent coils.)
It comes with one 18 dent coil and two 16 dent coils. The 16 dent coils are best for wide pieces with 11/0 Delicas and the 18 dent coil is best for thinner pieces.
