All of the patterns included are stranded colorwork projects. Because they are worked with two strands of yarn to complete the colorwork design, the socks produced are doubly-wooly warm. Once a month, for seven months, I designed and published a “Socks for Jeans” pattern. Debbie from Knitbin.com made up kits, which included the pattern and yarn, and she offered special pricing to all her customers. She continues to offer all the kits for the patterns in the series, and she continues the special pricing. Find the kits here: http://www.knitbin.com/Socks-for-Jeans-Kits-exclusive_c_1... Debbie kits the patterns with the designated Regia sock yarn. Regia are the sock-yarn people. I recommend using the yarn specified in order to achieve the results shown in each of the patterns, but you, as the creator of your own socks, are of course free to use any sock yarn and any color combinations you desire. Several of the patterns offer pocket options. And I have designed three pocket styles: a hidden pocket that is on the inside of the sock (see The Ripple Effect and Chocolate Parfait), an external, ribbed, add-on pocket (see That Lovin’ Feeling), and a pocket that incorporates the sock design itself (see Spring is in the Air). Although specific patterns show specific pocket styles, you are free to use any style you want in any of the socks. Simply follow the instructions for the pocket style you want and work them into the sock pattern you are using. Now, you can have all seven patterns, plus some words on color (yarn) dominance in one e-book for a fraction of the cost of buying each pattern separately.
