Uh...I know nothing about how to put one on a blog. Probably save the image to your computer same as you do for other links. I'll find the link for images in a few minutes.
Ahhh...I can't knit with those tiny needles and that tighter tension required for socks for long or my hands are bothered, too. I've got socks size 0 circs right now and it's taking forever so I've got multiple projects going. My preferred needle sizes are 5-8. I can knit for hours as long as I use the bigger circular needles or I'm doing something for shorter periods with the smaller ones.
I just got an ad for Patternworks and they are advertising Kollage needles and saying they are good for arthritic hands. They are square and you can get a soft or firm cable. Why anyone would want firm is beyond me, but I've not tried them. They are a bit pricey...right up there with Addi's.
