It's amazing what you can make with foil.
I've used this technique many times, and it's one of my favorites. This is another one that I will do a tutorial for one day soon. This week, I am helping to organize a local holiday fair. (My hat is tipped to anyone who has done this before. It is a LOT of work, but will hopefully be a success!) So after that, I may have my brain back again.
This technique uses crafter's foil, but you could certainly use a heavy aluminum foil in its place. Essentially, you glue interesting bits and bobs to a canvas, glue on foil over that stuff, burnish the items that you had under the foil, then decorate with alcohol inks. It's one of those projects that looks way more complicated than it really is -- and those are my favorites.
The only trick about these is that they are a beast to photograph! But they are gorgeous for the holidays.
