I have been wanting to make one with the 1 1/2" squares forever. I had a large amoupnt of them cut and just kept collecting. This was when I found out about being allergic to the chemicals in the fabric so I gave them all away.
Now, I prewash my fabric and started collecting again, but I collect the 1 1/2" strips.
One member on here told me a good faster way to make them is to sew several 1 1/2" strips together and cut them at
1 1/2" strips. You need several different sets, then you could sew those strips into blocks and then the blocks together. The matching of the corners seems like it would be easier because you are doing shorter areas at a time! Doing it this way would obviously give you duplicates, but you sew the blocks with different strip sets to make them look different.
There is also a swap on here for 1 1/2" squares for more variety!
