They are worth the money. I ordered mine from the Linus Project website and it arrived very promptly. I trim the edges of the blanket straight with a regular rotary blade and round the corners with a saucer. Then I use a ruler and the rotary cutter with the skip stitch blade in it to run a line of tiny slits about 1/2 to 3/4 inch from the edge of the fleece blanket. It's very quick and easy to use. Then crochet the edging through the holes for a very nice finished edge. You can find the instructions for this online.
