These little guys are filled with rice, or even scented rice, then popped in the microwave for a few seconds. Place one in each pocket, and your hands will stay warm and toasty. My kids loved these in their pockets while they were standing outside waiting on the bus. No more cold hands. Totally done in the 4x4 hoop, then hand stitched closed. $ 4.99
I tested these and when warmed in microwave (1000watts) for 15 seconds they stayed noticeabley warm for over 30 minutes, and barely warm for probably another 10 minutes.
