I adapted the original Puffy Baby Blanket pattern by my buddies on the @Bernat Yarns  Design Team, to take it from baby size to throw size. This version is for my 11-year-old-son, and I wanted it to cover his full body. To do this multiply gauge on pattern by desired width; Choose a multiple of 2 (plus 3). I also used hdc instead of sc as an edging.
