Altered to be in-the-round, and fit a travel cup rather than a mug.

I cast on 54 stitches (2 sections of 19 for the colorwork hearts, and 2 sections of 8 for two cable portions), and I did three rows of k1p1 ribbing for the top and bottom parts. With a size 4 needle for me - perfect proportions for a travel mug cozy - in the round - so no need to do colorwork on the “WS” of the cozy, like with the flat version.
