Hi Betty...when i did mine for my DGD, i used the "new" method - if you Google Bubble Quilt Method #2 --- it is the "new method" tutorial at
www.awaitingada.com. My front squares were 6" and back squares 4.5". I chose to put a "flat" border around mine - and my DDIL wanted the ruffle too. Here is a photo of that one.....which turned out to be about 33 x 48 plus ruffle. Because i used so many colors, I only purchased 3/4 yard of each color - but also used the fabric guide from the tutorial. Good luck with yours, whichever method you use.[ATTACH=CONFIG]514600[/ATTACH]
