I got the pattern for this from a book called Learn To Crochet Ripple Afghans. The finished size is approx. 31″ x 47 1/2″.
Since I do have the pattern, this will be an item you can pre-order/back-order. Just note that it takes a while to hand-make things. Plus, if I’m already working on a project for someone else, I’ll have to finish it first. But I’ll let you know when you contact me & I’ll keep you up to date.
