I don't do embroidery, so the I just tried this for the first time for thread bowls. (Wendy Hill's Incredible Thread-a-Bowls)The instructions for some of the bowls called for a layer each of both Super Solvy and Ultra Solvy. But when I saw the prices, I decided to just get the Super Solvy and try two layers of that. It worked perfectly. I don't know why the thread-bowl author calls for both, it was not explained.I'll brriefly describe the thread bowl process so this makes sense....You lay a paper form down on a work surface first (just for reference), then lay one layer of Super Solvy over that. Then you place all your threads (and other filler) for your bowl on the first layer of Solvy, extending out a bit past the paper reference guide. Place one more layer of Solvy over the threads. Slide out the paper form from underneat to get it out of the way. Pin the three layers together generously (Solvy, threads, Solvy). Sew (a lot) through the layers on your machine to hold everything together. Then pin sewn layers to paper form, so you can cut the sewn layers to correct size. Rinse 'most, not all' of the solvy out and place thread circle over inverted bowl till dry. Carefully remove and seal, and you have a beautiful thread bowl. These instructions are not as detailed as in the book, but I just want to give readers an accurate idea what I use the Solvy for.This review may not mean anything to embroiderers, but for 'thread-bowlers' please don't feel you need to buy both the Super and Ultra. This one works just fine.
