When I was a child, I had a pair of favorite mittens and matching hat that were thick and warm and had these cute little puffs in the stitch pattern. I have always wanted to duplicate those mittens. Here is my interpretation of them in a grown-up version.
These fingerless mitts or mittens have a side-gusset thumb. They are worked in the round in an easy-to-knit textured pattern which creates puffs that add warmth. Interlocking diamonds are created in wide stripes of color with a Tuck Stitch knit into the stitch several rounds below the needle while releasing the stitches above.
Make them with only one color at a time, use three colors for stripes as I have here, change it up by using only one or two colors or make it multi-colored by using up your scraps.
