Wow - I'm experimenting with some corduroy that I very recently purchased on sale, so am Planning a rag quilt. This Corduroy is very stretchy...hadn't realize that. I plan to X in the middle as I put the layers together, then sew them together. I plan a plain checkerboard pattern, but might throw in a few pinwheels for interest. I made one pinwheel and found that the seams are very bulky, which might make the quilt uncomfortable. I had to put fuseable facing on the blocks to make the pinwheels, which adds more work to it - and I'm not big on making work for myself!
I sure hope it works!
Good luck!
