Anatomy of a Shirt / Shirt Seas

I’ve been saving old shirts to make into a quilt. The first stage is unpick or “fillet” them into their constituent pieces. I was having a rummage in the bag the other day and I thought what a shame it is to cut all the parts into regimented rectangular pieces.What about just using the parts of the shirts as they are? How about starting with a central panel of upper back pieces, as above? And then I thought that they looked like waves on the sea, so I could spread them around and make a very rough sea with maybe a boat of two being tossed around. I think I need to play with idea some more.
