Thank you for the compliment, Salmonmac... No notes but I don't think it was very hard.
I crocheted two squares and two rectangles. The front and back were the squares and the rectangles were the straps.
Then, I sewed the two sides together, then added the straps.
Really, easy - piece of cake!
But, I confess to some problems as I had no idea how big to make each piece. I found something online that gave the dimensions of various sizes from baby to kid, chose one and went to work.
I really love the idea of not having a pattern... easy in this case but probably not so easy in something larger...
I always appreciate your good words... Thanks!
