Here is a link that Julie in NM posted earlier. It is a 12 1/2" block that is made with 1 1/2" squares. I liked the block but do not normally cut my scraps any smaller than 2". So I thought if I made that block with 2 1/2" squares I may only need one block for a table topper. Here is my version with those squares. It comes out to 24 1/2" unfinished but I am going to add two more rounds of yellow and 1 more round of scraps. Thanks Julie.
