I make the fleece blankets using two pieces of fleece. Put the pieces together on a flat surface or floor. Cut a six inch square out of each corner on each. Cut strips along each edge four or more inches long. Tie each two pieces together in a double knot. Done. No need to secure the two pieces. I have some made this way that are over 10 years old and still together. This use to be a fad, the tied fleece throws. Kids and teens love them.
