Ant Bee- I really love the chair socks! My grandma really needs these for her kitchen table. Currently we have felt pads on the bottoms but after a month they are falling off. We use the dining chairs often, so I must make some. She'll be ecstatic. Did you use a pattern?
They are working out really well, I used the Lily Sugar n Cream cotton and they are very smooth as they move on the floor. I have been thinking of maybe even adding in the felt sticky doo-dad under the sock for heavier chairs (or chairs used by people who might scrape a lot getting up and down in them.)
As usual, I sort of frankensteined from a couple of patterns flavored by my attention span. Here is the main inspiration: http://www.simplynotable.com/2011/featured-flashdance-chair-socks/
If you are on Pinterest and search "Chair Socks" you'll get this and lots more. I did knit for these, and there are oodles of crochet ones, too. Some have decoration on them (little buttons and whatnot). There is even a pin that has the foot of the sock shaped like a cat's paw! (That's not a pattern tho, just a thing one could buy from japan.)
