Sew four square strips to the other two edges of the background square. Press.
Assemble the finished blocks into four rows of four blocks each. Quilt and bind.
If you do make this quilt, I'd love it if you linked up to my weekly Let's Make Baby Quilts! Linky Party. There's a list of my free baby quilt tutorials over in the sidebar and you can find out when new ones are added by either following my blog or liking the Let's Make Baby Quilts Facebook page.
