The problem with me is that I am not good at taking pictures. These things do look different in real life.
I had an old and cracked plate, a nice flower napkin, some glue and some foil. I used PVA adhesive glue for this plate.
Here is my decoupage how to:
First I cleaned the plate well and tried to remove all the oil from it. You may use spirit to do that.
Then I sort of crumpled the foil, tore it to pieces and started to glue them one by one to the outer circle of the plate.
Then I cut out the flower pattern out of napkin and glued it to the middle of the plate and partially over the foil parts. I also glued several bids just to make it look nicer.
