Needless to say, I have been collecting these for a good while now.
You'll be surprised how quickly it happens.
So start with a sturdy base. I like to use a soap box.
Tape it up with masking tape, and if you want to pretty it up,
you can cover it up with snippets of paper.
You can also put those old cassette cases to use,
simply tape the opening close and use it as the base for your stamp.
Use a very tacky glue ( or a glue gun) and then it is as easy as gluing down the bottle caps
to the surface of your base item.
Let it dry and in no time you'll have a bottle cap stamp....made completely out of supplies
you would have thrown away anyway.
This is my collection of bottle cap stamps.....start your own.
and this is what it looks like when you put it to use.
