I love working with stencils like these. [Item=Diamond Stencil Sheet]
I think it would be wonderful to have transparent overlays for the various "cutout" sections so it wouldn't have to be white -- or even all the same color. What if the Circle Stencil Sheet had overlays you could get to fill in the inside of the border, but not inside the circle? Or if the triangle one had separate lower and upper overlays so that you could create your own 3 section (various colors?) background by using the original stencil with separate upper and lower overlays?

These are so fun to layer, I'd really like to see even more options of things to do with them.

I'm trying to visualize how this would work. They are transparent already,. The thing you see that is not white is the part that you can see through. If you want the white parts to not be white, you can't make them transparent also, because they would show the exact same thing that the non-white parts would. That is to say they wouldn't be stencils.

You are asking for another layer to put on top of them that prints something in the white parts only instead of a filter over the whole thing that you can stand in front of? They'd have to be something specific. What do you want these HA picture frames to look like?

Yeah -- I want transparent overlays for the white parts so that we can decide if we want to be standing in front of or behind the overlay part. For example, I may wish to have some small crittery thing be behind the overlay and have the color tint apply, while I am standing in front of the entire thing.

I would love it if I could have overlays, like on my current HA, where I could change the white parts without having to tint the entire thing.

EDIT:

examples -- note the "ethereal" feel

Ooh, pretty!! I like. More stencils please. Not sure how this would work, but I like the idea!
