I love that blue and purple one! I crochet, but mostly scarves, blankets, and other baby/kid clothes. I made some cute skull hats for my girls and my hubby last Christmas. Working on two baby blankets for friends of my mother right now.
Those look great and it's a clever idea. I don't crochet (my grandmother did try to teach me ) so I can appreciate other people's creations. I hope they sell well for you.
