I saw in some crafty shop these stencils at a ridiculous price, not that I needed or wanted them but I thought I'd make my own and share if anyone else did and not pay stupid amounts of ridiculous money!
The stencil when printed sits over the sticky note, you draw it using a pen then use it.
There are 3 models
Fits any regular pen, tested with a standard biro as seen in images, the fit around the sticky note is snug so shouldn't move much when drawing but heads up!
The author marked this model as their own original creation.
