Not only sewing it but blogging it. I have made basically the same burp rags and baby blankets for many a baby shower.
I sew most of the way around and trim the corners.
And I wait until the next time I sew to turn it right side out, and zig-zag around the edges.
I’ve come around to doing the same baby blanket for every new baby, but hey, it’s a classic, right? Carry on!
