I have a huge stash of fabric like all of you lol....but what I always migrate to, are my scraps. I love to dump it all on the floor in my studio (I have to block my Teddy (dog)) and just sort through them and get inspired with the shapes. I usually just start joining and when I run out of areas, I just start a new section and I keep making sections of fabric. Then I take a look at all the sections and figure out how to join those. Usually I have to square the sections, and that makes a new shape also. Then I will add a regular block or a scrap one and so on. Sometimes I plan a design, like when I did the starway to heaven.

It started out as mindless until I got really inspired. There are many pages to this project but with lots of information if you want to start your scrap quilt you can see how I started mine....
