Introduction: Knotted Fringe Fleece Pillow Cover
Fleece and what's sometimes the fuzzier felt-ier version, called blizzard fleece, is not impossible to work through a sewing machine. But add in some folds, as when making a pillow cover that opens in the back for pillow form insertion and removal, and it's not meant to be. Hand-sewing can leave sides too easily tugged apart with all the lovable stretch of the material, and that stretch could equally be problematic for zipper fastening.
Fringing and knotting the sides, like we sometimes see displayed for fleece blankets, comes out very nice, is a kid-safe project exercising fine motor skills and engaging creative choice, and lends the super soft and potentially warming fabric to an especially comfort-intended application - decorating a pillow.
