I love this Tunisian crochet stitch (when I learned it, it was called "afghan stitch").  I don't do a lot of crocheting, but I have made several of these little bags out of different yarns and slight variations of style.  This one is about 7-1/2" x 6", and is lined with the same dark red flannel that the hand-applique'd heart is made from.
