A photo of the crazy 9 patch class we did at quilt club on Tuesday. It turned out a lot better than I thought it would. Used leftover black/white plus some green squares to start.
To do this you cut 9 squares of fabric, all different if possible, Stack them and cut through vertically at an angle through all the layers. Keep the edge of the cut at least 1 1/2 inches from any edge. Take the top piece from the smallest section and put it on the bottom of the pile. Sew them all together. Keeping them in order, press the seam open and restack in the exact order you sewed them in the first time. Make a second vertical cut through all the piles, move two of the pieces from the smallest section, to the bottom of the stack. Sew again. Press, restack, cut across horizontally, move 3 layers to the bottom of the smallest section. Sew them all together, keep them in order. Press, make the 4th cut horizontally, this time move 6 pieces of the smaller section to the bottom of the stack. Sew again. Press then square up all the blocks to your smallest block. Repeat this with 3 more stacks of 9 fabrics. This will give you 36 blocks, This is set 6 x 6 blocks with a 3" border around. Really good way to use up fabrics. I started with a 9 1/2" square to start and ended up with 8" blocks. You can use any size starting square. One in the class used 18" squares to start, one did 12 1/2" squares to start. So you can figure about 1 1/2" to 2" smaller square in the finished block that the square you started with. If you want larger quilt, keep making stacks of 9 until you have enough to make a quilt the size you want.Have fun with this.
