From the pattern description:

Tiny bobbles are used for these mittens - larger bobbles might be a bit overwhelming - and they are worked on the back of the hand only to keep the mittens practical as well as fun. The bobbles mix up the order of the colors in this yarn.

Pattern includes stitch chart.

Malabrigo yarn suggestion from JimmyBeansWool, which sells a kit including one skein of Malabrigo Merino Worsted yarn.
