I may have 1 or 2 blocks sitting around but, I'm a little OCD and try to finish the projects I start. But I almost never use a pattern and make a quilt exactly like it says in a pattern or book. I have to put 'me' into it and that means changing things to my liking. The one quilt I made using a bunch of random blocks was the dresden plate. I taught a bunch of classes and when I teach a class I make a sample along with my students. So I had about half the blocks I needed for this quilt. So, I just made more and put the quilt together. I have a bunch of table runners from a beginning quilting class, too. One for christmas, one for easter, one for 4th of July, etc..... you get the idea.
