For an even knit I suggest carrying yarn in the same way each time. I did red on top and white underneath. Pictures later in the pattern of examples. Gauge is somewhat important so your cozy fits
an actual can! Different yarn weights - even if they all say worsted weight can vary in thickness which can vary the size of your cozy when it comes to length. The red was Red Heart used in the example, but the white was Caron Simply Soft and it wasn’t as thick. Can cozy knit in the round.

The yellow circle was knit seperate and sewn on after emboidering, “Pop Corn” onto it.
