I enjoy making shirts and sweatshirts for the different holidays. I bought a plain pink t-shirt at Wal-Mart and embellished the front with a heart yo-yo and flowers that were inspired by the new Fleurettes that Stampin' Up! is carrying. I have pretty limited crochet skills, but I like they way that they turned out.
If you are interested in making heart shaped yo-yos Penny Sanford has a tutorial that gives wonderful directions.
