My design wall is still covered with t-shirt quilt blocks, so I laid all the Scrap Jar Stars on the floor. Based on experience with last year's quilt, I knew I wanted to have a 5 x 5 block layout so the final quilt would be a decent size.
I've got 19 blocks, so I need to make 6 more blocks before I can start assembling. I don't know if I'll have time to make the blocks during December, so I may carry the SJS blocks over to next year's RSC.
Other RSC quilters are working with lime green or otherwise finishing up their Rainbow Scrap Challenge projects and you can see all their results over at Angela's Soscrappy blog.
