At an antique store in Texas I saw a cool antique trivet that looked like a bunch of grapes. It was crocheted onto metal bottlecaps, and looked like this one on Etsy:
It looks pretty easy, and a perfect beginner project for crocheting with thread instead of yarn, one of my craft goals that I want to achieve this year. And I will have no problem collecting bottlecaps seeing as how the fiance loves to homebrew.
Here are some instructions from a 1955 magazine. This is definitely going into the craft to-do queue. Wish me luck!
