Hi. I made a very large T shirt quilt for my husband. I looked at every free tutorial I could find. I think this one is very good. I purchased it on sale from Craftsy. Sara Snuggerud does a good job. They’re having 60% off now.

I stabilized each block with Pelion SF101. If you don’t stabilize I don’t think it turns out as nice. I also sashed. Picture below. If you have any questions PM me.
