I like to knead tickly blankets/yarn. The yarn has to have a specific texture so that when I draw the loose threads through my fingers, they have to tickle--most yarn is too soft or comes apart too easily or has very little texture or semi-loose threads at all, so I find it disappointing. But every so often I come across just the right kind of yarn, and especially when it's knitted into a blanket or some other article, I find it soothing to run the tickly fibers through my fingers. (Often when in the yarn section in a store I'll feel up the different skeins of yarn as I go by. )
When I was little and would do this to my blanket I would call it my "sewing blanket" because I imagined the motion of my hand toward and away from the blanket was like my mother stitching with a needle.
I also sometimes rub my feet together, or rub a foot against my leg, things like that, especially when feeling ill. Sometimes I'll rub my hands together/wring my fingers or pick at my fingernails. And I pull or chew the dead/flaking skin off my lips, but that seems to be more of a compulsion/boredom issue than a real "stim."
When nervous or bored I'll often repeatedly rub, twist, or pick at something in my possession, like the straps or leather bits on my purse, or a paper towel. I've mangled some things this way.
Other things I find soothing are the smell of rotting leaves (spicy) and damp earth, picking up and handling and flipping through books (oh, the heft and the covers and the smell and the pages), and the shushing sound of wind in leaves...I already have the books and the tickly blanket, now if my room smelled like rotting leaves and sounded like shushing leaves, I'd be set.
