1 layer of flannel, serged around the edge. These are great for laying on the floor for tummy time, putting over baby in the carseat or stroller, etc. Larger than store bought receiving blankets. Rounded corners. Just under 1 yard of fabric. Brand new, homemade. Free random bib with every blanket until I run out of bibs. They're ok, practice ones so I'm not comfortable selling them.
