I used to have a really obsessive hobby in covering anything and everything in pretty paper. Decoupage is very therapeutic. One of the things I’ve previously made were my night before my wedding shoes that I covered in a video game theme. Recently a friend who is getting married asked me to make custom ones for her and her theme is some Marvel comic characters.
I therefore proceeded to make some wedding shoes. Decoupage is super simple especially if you don’t get caught up in the expensive kits. All you need is some PVA glue; water, a brush and some light weight paper with a pattern. Very simply you mix the glue with a splash of water and brush on whatever item you want to cover. Then smooth on the paper and coat again. That very simple is decoupage.
There are however some tips I can give you from over the years. The surface of whatever you are covering needs to be clean and dry. It helps if it’s shiny to be roughed up a bit. For example these shoes were patent gloss so I sanded them slightly with sand paper and a nail file. You should also try to use neatly cut; not torn bits of paper to keep it neat and use as small as is sensible especially around curves. I also like to cut out some blocks of matching colour from the same source. For example on the Green Lantern shoe I cut up small pieces of green from the comic book to provide a little background.
Finally PVA is waterproof to a degree but if you want your end product to last longer I’d recommend a light coat of craft clear spray varnish in very thin layers to prevent white bubbling.
