I bought a kit from Jinny Beyer, and although it was somewhat expensive, it was fabulous! It took a while to put together, but I had it quilted, and donated it to a charity fund-raiser, and I honestly think it was the prettiest quilt I have ever done. I almost cried when I had to give it up.
The nice thing about the quilt kits is that you don't have to run back to the fabric store because you still need 1/2 yard of that one material that you need to finish your quilt. :)
