The Medford Public Library presents an Introduction to Block Printing workshop for teens, led by Debbie Sheehan of Lagniappe Arts and Crafts. Block printing involves carving an image into a material and then using the material to print that image. In this workshop, you’ll learn about materials, safety, image selection and modification, and you’ll carve and transfer your own image. Sign-up is required through the registration form on the library’s online calendar.
