Here is the video Cat Bordhi made about knitting on the go. (a.k.a. knitting as exercise!)
My recent "on the go" project is the thrummed mittens I learned to make thanks to Leslie at Ewephoria Yarns in Pocahontas.
This is the final product:
And this is what they look like on the inside:
The lining is tufts of alpaca which make them feel like luxurious pillows of warmth on your hands. (Given the overheated state of my hands 90% of the time, I'm giving these to my DD who has cold hands and will soon be walking across a cold, wintry campus!)
I've found the process of thrumming a bit more tedious than I like with knitting, however I'm very glad to have learned the tecnique!
