I designed this for my fiancée to make it easier to make certain shapes that she does a lot. There are three versions of the stencil. V1 was the first version that I made for her. It has the outline shape that she uses a lot, and the boxes and circles that she also uses sometimes. The lines were my idea just in case she would want some, and I needed to fill the space. V2 just has smaller boxes because she told me that the boxes were just a hair too big. V3 is the current iteration with several shapes where the lines were. The camera shape was just something I added because I had designed it a few years ago and there was space. The thumb tack (without the pointy end) is something she wants to try using but she hasn't ever done it before.
I will upload more of these designs as she requests them. She currently has a stencil that she carries around with the journal that is only used for a handful of shapes so maybe I can make a new version that only has those shapes.
