That wasn't as bad as I thought. But I guess in a way I cheated, I used Triangulations. I didn't have a lot of black and white scraps so it was easy just to cut the pieces needed from yardage and fat quarters. Now I have lots of black and white scraps!
It doesn't look like it but all 650 mini-blocks are in the there. As a matter of fact, it's more like 725 as I got a little carried away with step 3 and made 75 extra. You can read all about it at http://quiltville.blogspot.com/p/orca-bay-mystery.html
This in another of the red quilts I use at Christmas. I call it 2592 Red Triangles (not very creative with names)- perhaps Out of Focus would have been better. I finished it in February 1998. It measures 90 x 90 inches. It won a red ribbon and an award of excellence for machine quilting at the 1998 NC State Fair.
It doesn't look quilt so much out of focus on a close up. I have washed it quite a few times and it is very soft and comfortable. I use it on my bed quite a bit.
