Just over 2 years ago at a quilt class I was shown how to do a disappearing 9 patch. I did not have a lot of experience quilting so I wisely decided to buy some cheap Halloween Fabric from Walmart. I made a pile of blocks and then got sick of it and put them away. I found them when looking at all my fabric getting ready to move and decided to use them to practice free motion quilting. This is what I found.
I am sure they were meant to be disappearing 9 patch blocks. They all are like this. I don't know how I managed it but I completely messed up a very easy block.
