These blankets can be any size you would like. Just when 1st cutting the fabric, be sure to add about 4 inches to length and width to allow for ties.
Lay 2 sheets of fleece together. Make sure the wrong sides face each other.
Line the edges up as straight as possible. It's okay if they're a little off.
Cut out a 2 inch x 2 inch square on each corner of the fabric. Make sure you are cutting through both layers of fleece.
Along each side, cut strips of about 1 inch wide and 2 inches long. This doesn't have to be exact.
Every other strip is folded up to see this better.
Now you start tying the two overlapping strips. Pull firmly, but not too tight or the fabric will bunch together.
Be sure to tie each side.
