toe warmers

two pairs of socks

 + 4 cups of long grain white rice (the cheapest brand - it's not for eating) 

÷ into one cup for each sock 

~ 10 minutes at the sewing machine on zigzag

× 1-2 minutes in the microwave = 

four toe warmers*

*also nice for warming hands or for achy backs or for knotted necks or for crampy baby boxes (not my term for a uterus, but i guess it works)
