Another idea is knitting slippers - there is an organization called Operation Toasty Toes - they have some websites, just google toasty toes. These are easy garter stitch slippers. I have made many of them, also for myself and just about everyone I know. Good bed slippers on cold nights.
I just made one of the helmet liners and it turned out pretty well. They prefer all wool for those and Patons Classic Merino Wool is a good choice as it is very soft.
