This is your starting point. Remove the pop top. Notice how the (2) on the left of the photo are lifted ? That is because this is where the pop top was connected to the can and you need to flatten it out, like the one on the right side of the photo.
This is easily done with a pair of pliers.
Now that you have the tab ready, start adding stuff to it.
Wasn't that super easy !!!!! So run in there and grab those cans and remove the pop top. It's not difficult. Just bend them back and forth a couple of times and they will pop right off.
You could add a brad to the smaller hole, then run a ribbon through (2) of them and use it as a closure of your album or for a page in your album.
Take a look at these (2) photos again
Look at the tab on the left. There is no metal on the section that is attached to the can. Now look at the one on the right. The metal is still on it. All three of these came from Coke Zero, so it has thing to do with the can its self. It all depends on how the metal breaks off. If you want to add a brad, as I suggested above, you are going to need (2) of the pop tops with the hole in the center. Of course you can use metal cutters and remove that piece entirely. Then you will need a large brad to cover the hole.
That's it for now. Happy Scrapping !!!!
