INFO:
To decoupage, start by cutting up pieces of soft, flexible paper to decorate your item with. Next, wash and dry the surface of the item so it's nice and clean before you get started. Then, use a paintbrush to paint glue onto a small area of the item. Once the glue is on, press a piece of paper over it and smooth it out. Repeat with the rest of the paper and then let the item dry for 8 hours. Finally, apply another layer of glue over the decoupage to seal the paper in place.
