Make Your Own Wrist RestRice and a sock--that's all you need to make your own wrist rest. If you prefer, you can use other pellet-like fillers, including cherry pits, beanbag filling, or anything else you can get your hands on. If you use rice, however, you can heat the wrist rest or cool it to help your overworked wrists relax.Pour the Rice Into the Sock\nPour rice into the sock you've chosen (an athletic sock works best).\nTie the Sock\nTwist the sock to close it, and make a nice, strong knot. If you\u2019re supercrafty, you can try sewing the sock shut.\nRice Sock CompleteYou're done--just slip your creation under your wrist. Feel free to adjust how much rice is inside the sock to make for a firmer or squishier feel. For more projects, see the rest of our DIY Tech Accessories how-to.
