Helmet Liners that she knit for Nicole's husband, CJ who is in the army, Amber knew it would be the perfect gift for her now fiance! She was finished in no time at all and this helmet liner has kept him warm even on the coldest of nights while he's jetting around on his scooter. A free pattern found here:
Knitted Helmet Liner, you could make one for those who ride bicycles, ski, or any outdoor activity that will keep his/her head warm since it fits both genders just fine! Or, make a few and send to the address listed on the site to give to much deserving soldiers!
