Looking at the depth of the lid (these aren't the two-piece lids that come with empty canning jars), I decided the Movers & Shapers dies from Sizzix would probably work best. The only one I had that might possibly work for my project was a small keyhole die. It was almost the same depth as my lid, which was about the depth of an original Sizzix die, so I knew I could safely feed it through my Sizzix Big Shot.
Once I had the Movers & Shapers die in place inside the lid, I realized it wasn't as tall as the sides of the lid, which meant it wouldn't make contact with the die cut machine. I knew I needed some rather thick shims, so I reached for another Sizzix die to cut a few circles from heavyweight chipboard.
One pass through my Sizzix Big Shot provided enough circles to create the height I needed.
I placed the lid and keyhole die between two cutting plates and ran them through the Big Shot. It cut through the lid pretty well with just a small piece that didn't cut completely. I used gentle force to separate the stubborn areas.
Now for a word of caution about using the die in this manner. The steel-rule shape in my die pushed through the wooden die base slightly, either because the total thickness of my shims created too much pressure (looking at the picture above, I think I got carried away with the circles) or because I needed to use a more solid shim to provide a sturdy base for the die (or both). My die still works fine, though.
The cut edges of my lid were a little rough, so I used a file to gently smooth them.
Since my lid was gold, I decided to use Martha Stewart Craft paint in gold to cover the lettering. Nobody really wants to know they're drinking from a spaghetti sauce jar.
A few coats of paint later, my jar was ready to serve as a very large tumbler. I make no claims as to how well this will hold up to repeated uses (or the dishwasher), but it was fun to experiment.
Sadly, the Classico Spaghetti Sauce at Costco is now sold in a slightly different style jar. Time to move on to a new obsession.
