Now I've had these done for a good while now, but haven't gotten round to posting them. I made a bunch of finbgerless mittens for my local animal shelter open doors day and fair.
They are knit using various yarns from my stash - the pink/white one is dyed by myself with Kool Aid! They're all knit on 4mm needles (except for the blue-green ones, which are smaller and knit on 3mms) and have the same simple thumb construction (a hole with live stitches which you then pick up).
As much as I like making fingerless mittens, I won't be making any in the near future. Enough is enough! I do hope they brought some money for the animals though.
