I don't know about you, but my hands are always cold. Especially at work. I did a little searching online and found that it was pretty easy to make some. I looked at several different tutorials and came up with my own.
First, I cut four pieces of fabric (I used flannel) in 5-inch by 5-inch squares.
With wrong sides together, I stitched all the around, leaving a little opening one side. I clipped the corners, turned the squares inside out and poked the corners with a crochet hook (it was the only thing I could find!).
I filled each hand warmer with about 2/3 cup of rice. This seemed to be just the right amount for a 5-inch by 5-inch hand warmer. I sewed the little opening closed and was ready to heat them up in the microwave! I tried a few different times to see what worked best and found that 45 seconds in the microwave was perfect.
I actually used these at work today. Our office is quite chilly and my hands are always cold. I'm also going to be giving these as some Christmas gifts as well. I just need to make up a little tag with instructions on how to use. These little hand warmers are great way to use up scrap pieces of fabric and super easy to make. I know I'll be using them a lot this winter!
