It's well worth a try, CREATIVE. Whatcha got to lose by trying? When I wanted to make faux Van Gogh, I painted the back of textured clear glass. When I cut the sheet of glass there were a few chips around the edges, but most of them were covered by the mortar and grout.

Sonicmom - The chairs feel like they did before they were painted. If you want smooth, start with a smooth chair (sanded if necessary) and apply maybe three thin coats of paint. If you want to decoupage, there will be raised areas and how raised depends on the thickness of your cutouts. If they're wallpaper they will be a little thicker but if they're tissue paper or napkins they will be thinner. CEFreeman, I have three terracotta pots I fill in the summer and keep in the garage in the winter. I did latex and spar varnish inside and out and they've lasted for years. The decorations on them I used acrylic craft paints. These were something I just threw together fast just to get some color on my porch steps. I'm thinking these would be a great Girl Scouts project for Mother's Day! The checks were done with a flat brush and the dots were done with a q-tip. I quit using the saucers because when it rained or I sprinkled they held water and were drowning the plants. Then I have two matching ones I painted the same and I think I did not coat the insides all the way -- trying to remember. They stay out all the time. They got wet and then froze, then thawed, then started to disintegrate. :( I need to replace them now but they each have plants in them and they're not small pots. The other mistake I made was hand painting a small detailed design on them. You can't see it from the street. Duh me. Anyone know what I should replace them with? I'm thinking plastic is what will endure the weather. Does this cracking up happen to all terracotta pots? I love that your creativity is going. Be sure to post pictures! Grlwprls - My neighbor lost her bird bath in the same winter I lost my pots. I'll tell her about your dad's secret, thanks! Thanks about the chairs, too.

Not sure what you're asking about water, but I don't use water at all, just glue. Decoupage will fade if the paper/inks you're using are not sun stable. Magazine pictures usually fade for me, especially the reds. Some colors and inks are more stable. I usually use white glue, since I found a good deal on gallon size. Mod Podge always stays sticky for me, but I've heard they now make a version that hardens. You could use regular MP for most of the work, then use the hard stuff as a final coat, or final coat with a spray varnish or white glue. MP and glue don't need sanding between coats, but oil-base varnishes might, especially if they'll be exposed to wear, like furniture. One coat of glue is enough for me, more coats will give a thicker coating which you might like. You might want to cover the entire panel with a background paper (I like book pages, but wrapping or scrapbook paper would look nice, too, then lay out your pictures on top of that. How big is your panel? Sounds like you're putting a lot of different things on it. Might be nice to put your most important interest in the center, or maybe one that relates to the others. For instance, put a family picture in the center, then maybe if you garden with your daughter, put the gardening pictures near her. Does that make sense? It might help to lay out your whole piece before starting to glue (excellent advice I rarely follow). Cut out a panel-shaped piece of paper, then lay out the pictures in various ways until you're happy. A tiny bit of BluTak on the back of each piece would hold them in place temporarily but remove easily.
