I recommend Quilter's Cache. All sizes, all designs, whatever you would like to do. I see a pattern I want to use and I print it out. I have used the same patterns for years. I love them and their instructions are so easy to follow, not to mention they tell you how much fabric you need.
I love makiing Sampler quilts, which are quite easy in and of itself, and I usually make 12" blocks for my quilts and if I see a special 10 inch pattern, I just frame it with complimenting fabric. I swear by Quilter's Cache. Edie
