It says this is a 1 hour project...but I can't see it would take that long... I know my grandkids would love a soft snugly pillowcase...So I am going to make them each one for Christmas. I think my dog Maggie might even like one on "her" pillow...lol Also..this book has some tips... How to tell right side of fleece fabric. Gently stretch the fleece along the cut edge that has the greatest degree of stretch (crossgrain). The fleece will roll or curl to the wrong side. Pre\-washing is not necessary with fleece. When laundering outerwear fleece, best results are achieved with the use of powdered detergent. Since fleece is a by product of plastics, liquid detergent does not remove the dirt, but simply coats the fibers. Enjoy patti
