This RN coffee or drink cozy works best for plastic tumbler because it has a few extra stitches in the rows in order to fit the design in compared to most.

My finished product came out to be 9 1/2” - 10”.

The pattern contains 2 versions. In the round construction and row construction. There are written instructions for both and a chart if you are a visual person.

The pattern also contains instructions to crochet the heart beat in or you can opt to fill in the heart completely in red and stitch it on later. Especially if you are working it in rows. Because it does loose some of it’s definition when worked that way.

Any worsted weight yarn can be used. You may need to adjust your hook size. I crochet rather tightly, although I did my best to loosen up my tension. Your gauge swatch will be very important in order to fit properly.

Experienced crocheters can easily up size the main piece to turn it into other items such as totes, tablet covers and more.
