I have made many of these bags - so quick & easy. I used "Dick & Jane" panels for a group of 8 old-time friends (we gather at a place on Coeur d'Alene River each August - float the river, rubber duck races, hike, etc), We call it our Kindergarten class reunion - been friends since we were 5 - & we're 65 now. The Dick & Jane fabric panels seemed so right for this group - we learned to read with Dick & Jane.
I'm doing a tutorial for another group I quilt with (mostly for charity) in a couple weeks & several non-members who saw the bags want to join us for snap-bag-day.
