I designed this rack to solve one of my own problems in the studio.. what to do with all these new embroidery spools I found! I figured there were many options out there, so I'd just start to look for something that worked for me. Turns out, it was tougher to find than I thought. So.. here's my inspiration for fixing my organizational problems.
This rack holds 50 embroidery thread spools total (25 on each side, in rows of 5). The stand is just over 10 inches wide, about 12 inches tall, and the feet spread out 8" for support. Each spool holder is about the size of a Popsicle stick at 3/8" wide (10mm). You'll want to make sure your spools will fit into that slot as some may vary.
The rack comes as a kit in 12 pieces that easily snap together. No glue or special hardware/tools are needed. Feel free to paint or finish the birch any way you like.
