Anyone ever heard of this? Our local craft store is offering classes and I thought I might check it out. I do crochet and I just wanted to know if it's hard to do. I "googled" it to see what it is and it looks like it can be a real challenge. Do you think someone who crochets has a good chance with it? LOL I was reading the instructions but I'm better at visual so the class would be a great help.
