P.V.A is good for decoupage crafts. Decoupage is the process of embellishing an object with coloured paper. One bottle (must be white glue) is about $5
from the Hardware store.
Half glue and half water...mix very well.
Do a 'test' on a old cardboard box...to see how well it sticks, and use a paint brush, paint in portions, apply and get a couple of rolls of wrapping paper.
If it is too thin to stick add more glue...but 50-50 seems to be o.k.
Don't make up too much, until you know how you like the glue to stick.
Do Not use the glue full strength....
Cut the paper in different size squares.Apply to the box as you would like.
Overlapping is nice too.Let the glue dry just a tiny bit before applying the paper, so it sticks better.
Just have fun, do not rush.
If you go this way, would love to see the end product :)
For more info just type into Google ''Decoupage with P.V.A. Glue" or even YouTube.
Make sure your paper you are to cover the box, is not too light..as to pick up the original colour of the box and any writing on it.
If you look at the pic I have to the left, it is just a ordinary cardboard box, your project is bigger....but a box no less.
Remember to over lap the paper, so it gives a nicer appearance.
