I incorrectly assumed this booklet would include ways to make reversible items taking advantage of the fact that using two different yarns and flipping the double-ended hook (a.k.a. crohook) after each forward pass, the fabric created will be predominantly the color of one of the yarns on one side, the other on the reverse. But these patterns are all worked on one side only, as though the crohooks were double-pointed needles. You need to buy 3 or 4 crohooks of the same size. Where a variety of economical brands and sizes of sets of doublepointed needles is available at any craft store that sells yarn, crohooks are hard to find, not sold in udplicate-size sets, and more expensive. These patterns are identical to doublepointed needle patterns, just using a different tool. If you wanted to achieve a knit look via right-side-only crochet, a Knook would be simpler.
