These 4-patch blocks are made from 3½" strips (wof) one of each color sewn together. I then cut the strips into 3½" sections which were sewn into 4-patches. I got six 4-patch blocks from each strip. You could also do the 4-patches in black and white scraps.
All the 9-patches are from my scraps. I gathered scrap fabrics and paired them up. This can be random or you can pair them up any way you like.
Here is what I have done so far.
