Helmet Liner

Last week an Investigator in my office asked if I knew what a helmet liner was. Yes, I've seen them on line. I told him there are many groups out there that knit them for our armed forces. He said he has a friend who's son needed one and asked if he knew anyone who knitted. He called me and asked if I could knit one. YES!!!!! I told him I would give it a go. Fingers crossed, knitting needles and yarn at the ready......
Tah-dah!!! Finished! I love it!!
