What a neat site! I've added it to my favorites. I'm interested in learning applique this year and I'll definitely be using this as a reference. Thanks for sharing.
I agree with other posters that since the site is designed for newbies, having a variety of fabrics will help others to see the project's potential. Unless they start out as fabric collectors, a lot of people try to copy something they like as close to the original example. Plus, once they do one, they'll feel comfortable doing others for themselves or for gifts.
