There are many ways to make a fleece blanket, but adding a crocheted edging is my favorite. This blanket for Project Linus is about 36" by 55". The soft purple fleece is edged with 3 rounds of crochet. The first and last rounds are groups of 2 half double crochets. The middle round is one single crochet and one chain, repeated around. The variagated yarn is the color Monet in Red Heart Super Saver. The yellow was donated without a label.
I cut holes to crochet into with a wonderful specialty rotary cutter blade called a skip-stitch blade. You have to have rotary cutting tools, but as a quilter, I'm well equipped with rotary cutting tools.
You can order the skip-stitch blade from the manufacturer at skipstitch.com or from the Project Linus store. There are 3 varieties of skip-stitch blades. Use the "Original" skip-stitch blade on fleece.
I learned how to add an edging to fleece from this YouTube video created by one of the Chicago area Project Linus chapters.
There is also a Project Ideas page on the Skip-Stitch website. Be sure to click on the link under the video for written step-by-step instructions.
August 9, 2012 Update - The Skip-Stitch website has changed. A big Thank You to Karen C. for the heads up on the broken link. The video is now on the Skip-Stitch home page. Their Ideas page has a slide show and written directions for using the skip-stitch blade.
The Skip-Stitch site shows a foundation of single crochet and chain 1 in each hole, with extra single crochet in the corners. I usually do 2 half double crochet in each hole (4 in the corners). Depends on the look you want and the edging you plan after the foundation.
