I finished up a pair of rain mitts and would like to share the pattern with anyone interested in making their own.
I wanted a light, easy to make mitt. As few pieces as possible, lays flat for sewing together, and no bells or whistles. In lieu of a drawstring or velcro, they tuck into my jacket sleeves. They ended up weighing 20 grams for the pair, using 2.5oz WPB fabric for the back and wrist and PU coated ripstop for the palm.
I put the PDF pattern here if you'd like to view or print it.
If anyone does give these a go, I would be interested in any feedback.
