Mark on the inside of the box where the holes for screwing are – this will make life easier at the end of the project!
When the paint has dried, apply the Mod Podge – again, to all the surfaces you wish to cover
Gently lay the napkin onto your box trying to avoid getting any creases.
Fold down all the corners, trimming off any excess and smoothing down with Mod Podge on your brush.
When your box has gone tacky, gently poke some holes through the tissue paper so that you can screw the hinges back into place later.
Leave to fully dry and that’s it!
Screw the hinges back into place and decorate with any embellishments.
You could also line the inside of the box in the same way, just make sure the outside is completely dry first.
If you don't want to use a box, this process will work on any wooden or mdf shape.
I hope maybe that's inspired you to have a go ... I'd love to see pictures of any projects you make!
