I made a bunch of baby blankets with just fleece. I would have crocheted – but fast as I am they still take a long time and sadly, I just don’t have alot of time.
Fleece baby blankets are easy though.
Fold a rectangular piece of fleece (twice the length you are looking for) in half with right sides together.
Sew along three edges either close to the edge (1/4 inch) or farther from the edge and just trim to 1/4 edge.
Flip right side out.
Fold the fourth side edges in and sew within a quarter inch of the edge – continuing at that 1/4 inch mark all the way around the full blanket giving it the finished look.
