The Medford Public Library introduces an Advanced Crochet Club for teens in middle school and high school. This club is open to teens who already know the basics of crocheting: slip stitch, single crochet, half double crochet, double crochet, etc. If you don’t recognize or know how to do those stitches, try the library’s Beginners Teen Crochet Club that meets on the second Thursday of the month. Registration is required for this meeting through the library’s new online calendar.
