This 11 year-old (who happens to be my daughter) is making and selling large baby blankets on Etsy! This is the first one she has listed. She is working on a few more, and will have those listed soon also! She has been making these for a while now, but is just getting started with online sales.
These larger sized blankets are so great for swaddling! They actually stay wrapped up in these, unlike the regular sized ones you get from the stores.
