This winter I've been making lavender rice bags as gifts for friends. I've just been using whatever flannel fabric I have, making a rectangular-ish shape, and adding rice and lavender. For the first one I made that I gave to the boyfriend, I used dried lavender. But when I went back to the co-op, they were out, so I went with lavender essential oil. I decided to do top stitching on the bags as well, to reinforce them as well as to give them a more polished look. I really love the way they have turned out! I have about two more bags of rice left out of the 25lbs I bought, which made 7 bags. Not bad!
