I have a bunch of scraps leftover and may use them to increase the size as, at 50" x 70", it is a tad small for the dogs and myself if perchance we have a nap together.
There are a ton of patterns out there for pre-cut strips. Here is a link to a great site that has a good write-up on the different types of Irish Chain Quilts done in a traditonal way. By using the jelly roll I opted for a more scrappy look.
