I have used the Method mentioned above many times for Baby Quilts, Potholders and Mug Rugs.. Made 2 non pieced baby Quilts in one day to go to 2 different baby showers.. Used width of fabric and 1 1/2 yard length - Trimmed off salvage. We ( my Mom and I ) just layered top right side up, then the backing wrong side up on top then the batting.. Pinned carefully, sewed 1/2 to 3/4 inch all around leaving about 12 inches open for the Turning. unpin and trim corners if needed. Turn right side out. Smooth out and carefully iron seams, Sew around the entire outside edge about 1/2 inch in from edges. ( you can hand sew the opening too) then we tied them with embroidery Floss about every 4 inches... Babies don't look for perfection just something to cuddle...! ! One was so cute it had Fabric in Crayon colors with umbrella Print on top and the backing was the Raindrop print, other one had a Truck Print and a Plaid on the back in the same colors.( for a Boy ) That was many many years ago..
