My LYS has a project that has a different version of the helmet liner that is more like a beanie than a ski mask and more colors are okay. Since I don't know the actual designer of the pattern that I received at a KAL I haven't been able to post it on Ravelry but I do have it in a Squidoo lens (free pattern) and hope you will take advantage of it if you wish. All I ask is that you let me know how many you knit and donate as we are trying to track them and push ourselves to meet higher and higher goals. The purpose it to get every soldier a liner that wants one.

You can comment on the Squidoo lens or email me your donation count at firstname.lastname@example.org
Happy knitting and let no head go unprotected.
