I had some chanielle left over from making the straps of the dresses so I used it for the backing of the doll blanket. The pink polk a dot fabric I used for the binding was left over from making the dresses as well.
For the girls' brother I made a pillowcase. I used a good quality soft flannel with cars on it. I think he is going to love sleeping on it. I watched an online tutorial on how to make a "rolled pillowcase" to learn how to make it.
The thing I like about this method of making a pillowcase is that there are now raw edges.

The dresses were constructed in the same way. No raw edges. Here is the inside of the dress.
