This is what I ended up with when I took six 10' blocks and some 1'' black strips to our patchwork day. The first thing we done was to put the blocks together and do two cuts ( CUT 1), ending with three lots of six. Move the top piece from lot A to the bottom and move the top two pieces from lot C to the bottom. Join A & B with the 1' black strip and join B & C with the 1' black strip. You now have a new block. Do that to all six blocks. Press the six blocks and cut as in ( CUT 2). Repeat the above again and cut again (CUT 3). Repeat the above again. Trim the blocks. I ended up with 6 x 8 1/2' blocks. I joined tmy blocks together with the 1" strip, others used 2'' strips but you can use whatever you like. I made mine from Halloween fabric and made another two lots of blocks. I am going to make s small quilt for one of the boys. They like the skulls and
gruesome stuff. Another mystery solved.
