You've probably already finished this project, but for my Grandfather's 100th birthday, I took a box, similar to an old hat box and decopauged it. I took pics from his albums growing up and scanned them. I then printed them all in blue tones before I deco'd to the box. Then I poly'd it with a gloss finish. Looked great and was a hit!!
Go to an office supply house like office depot or office max and see what kind of paper they have available. Maybe something a little thicker than card stock. Ask and they will help you with it! You must have some great photos!!! If you get them turned into postcards, please let us see!!
Sounds like a great technique. I haven't done it, but if I were to do it, this is how I would start. Modge podge the pic and smooth it out with slightly wet fingers to eliminate the bubbles - it may take a little work, but be patient. Let it completely dry. When you pour the resin, I would place the plate on top of a small block, on top of waxed paper. Start pouring from the middle and pour slowly. You will know when to stop. As it is drying, go back to it a few times and gently, without touching it anywhere else, run a popsicle stick around the edges. If you get any drips that do dry, just dremel them off. I do that with tiles. I'd love to see a completed picture.
I'm so glad you started this topic!!! I was searching for it!! I've been covering items deco style and have a question about sealing items too. I usually attach paper to the item with slightly watered down glue and then modge podge over it. I then spray it with a clear acrylic spray. I have tried painting poly on it to get a shinier finish, but found it tends to bleed through sometimes, and tends to "yellow'. I really want a shinier finish than modge podge, and a more waterproof finish. I've used resin, and it is great for tiles, but I can't really use it on some things. I went and bought a new can of gloss spray today which I will be trying shortly. So, what do you use?
If your walls won't handle the weight, lean it up against the wall on a table. I do that on my mantle all the time. I didn't want to create a mega hole in the wall above the fireplace, so I just set the pictures on the mantle and lean them in towards the wall. If they tend to slide, I lay down a little of that rubbery shelf liner under the edge of them. Once again, fabulous piece!!
