I purchased fabric to make 2 flannel and 2 cotton receiving/swaddling blankets. I wanted them to be large, so I purchased 1-1/3 yards per blanket.
I purchased double yardage of each fabric, to make two identical blankets from each material. Therefore, I had to cut each length of fabric in half (lengthwise).
I also cut off the printed selvages.
For each blanket, press the hems under twice. You can press 1 inch or 1/2 inch, whichever works for you.
When at corners, I find it easiest to have the right side on top of the bottom side of the fabric. That way, you can sew all the way to the bottom edge and then back stitch and turn to follow the bottom edge. It also helps to pin the corner in place.
