Mystic Makerspace presents a class on how to make polymer clay pens at the Charlotte & William Bloomberg Medford Public Library. You’ll use polymer clay to create beautiful and colorful designs to cover everyday pens. Liven up your writing collection or give them as gifts. You’ll finish covering the pens in the class but will need to bake them in the oven at home to complete the process. This program is for ages 16 and over. Registration is required through the library’s online calendar.
