Thanks for all the suggestions! I found out that I could buy quarter yards at Glorious Color online and used that as my primary source but I also got some fat quarters on eBay. I have finished the last block and after seeing it all laid out I've decided to re-do about 5 of the blocks with different fabric. Here's a picture of it on the floor with the top row of triangles - all the other triangles are done but I ran out of floor room. Now on to the sashing, and I'm thinking about trying quilt-as-you-go rather than sending it to a long-arm quilter. Just not sure how QAYG would go on such small blocks. I highly recommend trying a Dear Jane if you are up for a long-range project with some challenging blocks. I've been sewing for 30+ years but I learned a lot, and my skills with applique got waaayyyy better in the process of doing this quilt.
