I think I would come up with a better way of the doing the final seaming so it could be removable for cleaning but for this exercise I didn't go into it that deeply.... The one thing I really like is the front and the back are identical - pretty neat.
Found this pattern on the internet (not sure where now) but it was a good way to do a simple intarsia project and sort of got my juices going to try something on a sweater I have been thinking about for my great granddaughter.....
