I thought about buying these but since, when I sew, I like my top & bottom threads to match I needed a way to store my bobbins with the spools. This wall rack will hold 128 spools. Total dimension 31 1/2" x 23 1/2".
I cut some wood "shelves"(1x4's cut in 1/2 length wise= about 1 5/8" wide by 30" long) & hammered in some nails on the front side(1 3/4" apart) for the bobbins. I found this great idea to secure the end of the thread to the bobbin. Its just clear plastic tubing I cut to fit the bobbins(found at Home Depot). I added thin molding to the front to hide the seam. The backing is a piece of beadboard.
Its so nice to be able to find what color I'm looking for. Now I just need to fill it up.
