Here’s my method for masking and weeding. This part of the tutorial is in video form only.
Plus, of course, all the other materials needed for your puzzle as described in Part 1.
(An older version of this video dealt with the problem of inkjet photo paper sticking too strongly to the masking. I no longer recommend using such paper, having found a better alternative, as mentioned in the video. But if you want to watch the older video, it’s here: https://youtu.be/pxZ4Tgz4G1o.)
Please leave questions or feedback in the Glowforge forum. Thanks.
