The first was for a preemie, who was only two pounds at birth, and 14 inches long. Fortunately for he and the parents, he grew out of it quicker than I was able to get it to him.
The other two were for newborns, and stretched a little more. I adapted a pattern from Christina's Sunshine Haven. In the first one, I decided to sew up the top, to make a hood. I only used one strand of yarn, so it is really stretchy.
The other one is made with two strands of yarn. I took off the top part, the head rest, and made it a little longer. I also made a matching hat. This is the one that was my favorite.
I asked the new mom for a picture of the babe in that one. I hope it fit!
