A fun activity to do with others and very customizable. Throw the rice pack in the microwave for a minute or two and then place on achy muscles or throw in the freezer and use as a cold pack. Works as well as ice and with no melting ice to contend with. Add scents for aromatherapy.
Step 1: BoM
Needle, thread, scissors, pins
Step 2: Sides
You can make your rice packs however big or small you like. Make sure you leave 1/4" seam allowance all the way around your shape (squares/rectangles are popular). Pin both sides together, wrong side facing out. You'll turn the pouch inside out after sewing so that the stitches are hidden.
Step 3: Sew
Sew 2-3 times around your design, enough so that you feel confident rice won't tear the stitches and escape. Leave a 1-2" opening. Secure all the loose threads with knots and glue if you'd like.
Step 4: Fill
Flip the pouch inside out and fill with rice. I've found that a funnel is very helpful with this.
Step 5: Close
Pin the opening with the raw edges folded inside. Ladder stitch the opening closed and secure the ends.
