My kids had been playing some games with plastic cups and one night, I noticed a huge stack of them leaning up against a wall in the living room. I was debating if I should wash them out and put them back in the cupboard to use at a gathering but that seemed like a fair bit of work given that the stack almost reached the ceiling. I started to think about what kind of craft we could make with them and the idea to make shrinky dink ornaments started to form.

Shrinky Dink Christmas Ornaments made with Plastic Cups. This is a great craft to make with multiple ages from preschooler to adult.I was really determined to make this idea work but it wasn’t as simple as I had imagined. Through a fair bit of trial and error, I was able to figure out how to make this concept actually turn into something and I’m so excited with how they turned out.

Before I get to how to make these, I will explain how NOT to make them so that you can learn from my mistakes. Initially, I just grabbed some clear plastic cups from the giant stack and brought out a pack of coloured Sharpie markers and asked the kids to draw or decorate them however they wanted. Then we put them on a cookie sheet and baked them. The picture below shows how they went into the oven and how they came out of the oven:

ornament attempt number oneAs you can see, four of the five cups shrunk down into funny little hat-looking-things. One of them flattened into exactly what I had pictured when I had thought up this project. At first, I thought maybe it was because that cup had been the one in the center of the cookie sheet but on closer inspection, we discovered that the one that flattened was a different brand of cup. The Dixie brand cups shrivelled into hats but the Polar brand plastic cups shrunk into flat circles.

The kids got to work decorating just the Polar brand cups and the next tray worked really well. All of the cups flattened into lovely little disks. That is when we discovered problem #2.

Shrinky Dink Plastic CupsI was not able to hole punch them after they had shrunk because the plastic had hardened too much. So those disks did not become ornaments.

Thankfully, my kids really loved colouring the cups and they happily coloured many more cups. I hole punched them prior to putting them in the oven this time!

Shrinky Dink Christmas Ornaments made with plastic cupsHow to make shrinky dink ornaments:

  1. Draw with permanent markers on plastic cups. (Remember that they have to be Polar brand!)
  2. Hole punch the cup.
  3. Place on cookie sheet and put in 250° oven.
  4. Turn the oven light on and watch until the cup shrinks down to a flat circle. Note that only the ornament in the middle of the cookie sheet will be completely flat.
  5. Thread a string through the hole and hang.

I’m very pleased with how these turned out and glad that I didn’t give up when the first few batches didn’t go well because they are really lovely. It was fun to see my kids’ creativity come out in their ornaments.
