I am going to paint a quilt block on the side of my shed. I'm thinking a big gold and yellow Mariners Compass. Anyone do this? Any tips? We just moved to a park on the lake and I have a 10x10 shed that needs painted. I am also going to put a little garden right in back of the shed, which is the side that will get the quilt. If all goes good, I might just do squares all the way around.
