Two color seed stitch mitten pattern

I made a pair of seed stitch mittens for my daughter many years ago. because of carrying a second color every other stitch the mittens were quite warm. I’ve lost the pattern - it was in a book of two needle mittens. Now want to make them for grandchildren. Any help would be appreciated.

Here are several 2-needle mitten patterns. Find one the right guage for the yarn you’ll be using and switch to your seed stitch pattern.
