Todd Paschall is an amazing crochet artist who has developed an equally amazing crochet technique he calls “Crochet by Numbers.” Pictured is one of his pieces, and yes, that is actually made by crocheting with yarn, simple ol’ Red Heart acrylic yarn in fact. On his web site, he has free patterns, a gallery with more fabulous work he and his students have done, and more information about how this method works.
In addition to selling finished work and teachinf others his technique, he also creates custom patterns from photos. He has recently set up a group on Ravelry for those who want to learn, share, and of course, get help along the way. When you see his work, you realize how he is not only an artist but an innovator, taking crochet to a level way beyond your typical granny square to say the least!
