The halfway slippy mug rug uses half double crochet and slip stitch to create a subtly textured design. Mug rugs can be a fun alternative to standard coasters, especially in the summer! This pattern is free online at my website, and it includes a video tutorial to walk you through the pattern. It is also available as a PDF purchase, which includes this design and two other mug rug designs (each of which are also available online for free with video tutorials).
