A few years ago I got out my knitting needles and somehow remembered how to knit and, pretty soon, I could knit and read at the same time! Being able to read while knitting was the key for me -- multi-tasking keeps my A.D.D. brain properly engaged!
These took about 6 hours each to knit. The yarn costs about $6 per.
It's fun to have a variety to choose from -- especially when they coordinate with your gloves or with your outfit. I could just go on knitting forever as I find fun new yarns (sometimes in dumpsters)!
Or they make great gifts!
