I have found a way to make bias binding really easy. Explaining it won't be so easy. Begin with square of rectangle piece of fabric. Fold the bottom right corner up, fold the top right corner down, just like like making a paper hat. Here is the tricky part. take the bottom left corner and fold it up toward the top right corner so that you're folding the edge along itself. it should make a strange looking rectangle shape. Make a narrow 1/8 inch cut to remove the double fold of fabric and cut your strips with a rotary blade the size you want!
