This is My Tutorial on how I personally decoupage an Altoids tin. The finished tin is really smooth. You can use this technique on so many things. I like to get the big cookie tins and make jewelry boxes out of them
The possibilities are endless.
Here are the Materials I use:
I use other materials too of course but these are the basics. I don't use Modge Podge at all. I had a bad experience with it in the past. (some of my tins would rust whenever I used it and it would show through the paper,that was when I was putting pictures inside the tin and not painting the inside, paper directly on metal. Also sometimes it would peel, plus I hate seeing brush strokes.)
Step 1: Get a picture and size it to what you want. There are templates online if you want to be exact.
here is a link to one. http://wrapcandy.com/community/uploads/newbb/3482_4613c8c5bd652.png
if you don't like that one you could always find another one or scan a tin yourself.
Step 2: Spray the printed picture with the Matte Finnish I have pictured. It doesn't have to be that kind, just a spray to prevent the ink from running. After it is dry cut it out. (If it looks a little fuzzy when it is dry don't worry about it. It will turn out clear)
Step 3: Clean the Tin and take the lid off. Spray paint the bottom whatever color you want but make the top white. I found that if you spray paint the top a darker color than white the color will show through and make the picture darker. If you don't want the top to be white you could always paint the back of the picture white and wait for it to dry then glue the picture to the top.
(I forgot to peel the sticker off the tin on the left. oops. This isn't really a big deal since I am covering it with a picture anyways)
TIP: I use Plastic dividers (something plastic. It was also pointed out to me that wax paper works too) to put the tins on before I spray paint. If you use newspaper or cardboard once the paint dries, when you go to pick it up, it usually leaves bits of paper or cardboard stuck on the tin. Using something plastic prevents that
Step 4: After that dries take the paste (or any adhesive you choose. Paste works just fine because after you spray it with all the coats of spray the picture isn't gonna come off.) and glue the picture to the lid. Add glitter now if you wish
Step 5: Spray the top and bottom with the crystal clear enamel. (rust-oleum) wait for it to dry.
Step 6: Spray the top and bottom with the triple thick clear glaze. (I use 2 or 3 coats waiting for it to dry in between)
Step 7: Assemble the tin and you are done
