When my son was a baby, he had lots of receiving blankets. As he grew older, of course, they weren't needed. I gave away several, then one day I needed a toy bag to take to Grandma's house.
Fold the receiving blanket in half, sew the long side and one short side making a bag. Sew a fold at the top, leaving an opening for a draw string. Insert draw string and you have a toy bag, pajama bag, or laundry bag. Receiving blankets are usually flannel, so I also used a few to make pillow cases for him. They were warmer for him in the winter and I had enough to generally get him through his colds, flu, ear infections when pillow cases get slobbery and need to be changed.
