Tutorial: plastic keychains

I know a ton of you have been waiting for this one. Teaching you to make your own plastic keychains!

To start off, I think the biggest question everyone has is what I use to make them. I work with shrink film. You might be familiar with Shinky Dink brand shrink film as a kid. I use Grafix brand white inkjet shrink film. The inkjet kind is relatively pricey compared to the regular kind. If you’re using regular, I don’t recommend you stick it in your printer. Sharpie markers would be good for that.

Alright, now open up the file with the images that you’re working with. Make sure your images are a lot bigger than you want your finished product to be since they shrink significantly.

image

You’ll also want to lighten the opacity to about half. I go somewhere between 50-60%.

image

Now print your image out! I’ve found that it works best for me when I have it at the plain paper setting, and standard print quality.

image

Holepunch with a 1/4” holepuncher BEFORE you shrink them. It’s so much more work to have to punch holes when your plastic is thick!

image

Cut out your design, leaving the amount of border you want.

image

image

Set them on a tray for convenience. An aluminum foil sheet works too, but I recommend cookie trays because they are easier and quicker to get out of the oven.

image

Preset heat. Your shrink film package will tell you what temperature to set it at, but I find that it isn’t always accurate for me. I generally set temperature to 350 degrees or so.

image

Put them in the oven. Remember to keep track of time! I leave them in for about a minute and a half.

image

After time is up they should be super small! Magic!

image

If your charms are not flat, put something heavy on it right out of the oven when they are still hot and malleable.

image

image

If you’d like to, you can seal them now. In my last two batches, I used clear topcoat nail polish. The problem with that is that I need between 3-5 coats of it, and it takes a while to dry. I’ve been experimenting with modpodge.

image

For lariats, you can use jump rings or lobster clasps.

image

Here is one that I made that wasn’t sealed. The finished texture after shrinking is a little bit rough. There’s nothing wrong with leaving them unsealed, but because they are inkjet printed, the colors wash right of without protection.

image

This is one that was sealed with modpodge. The colors become a little more vibrant and smooth and water resistant. Things often get stuck on when applying or drying so be careful.

image

These ones down here were sealed with clear nail polish. They come out shiny if you put enough coats, but the grainy texture will still be there.

image

Well, there ya go! Have fun making your own keychains!
