This is a quilt my students did. They each made a block and I had to figure out how in the heck to lay them all out. I took pictures of all the blocks hanging on the wall. I made a few colored squares in Excel, and then cut the blocks out from the pictures I took, and put them in Excel. And this way, I was able to easily move them around to get an arrangement I like. The blank spaces were for AWOL quilt blocks, which did eventually show up
