Have you seen this cool new stencil from Crafter's Workshop?
I grabbed it and some pens to play with while sitting around waiting for my daughter to get out of dance....
...perfect for Halloween! I used painters tape so I didn't need to worry about it moving around, and my Slicci pens
(you really need a pen with a tiny tip for this kind of intricate stencil - my gel pens bled under it, and even paint is probably too thick. Fine spray paint like Glimmer Mist might work.) I might not have had the patience if I'd not been stuck sitting there an hour anyways - but if you have downtime, this is a portable, fun lil project!
