Making your own Winnie the Pooh hard plastic keychain charm is a great project that parents and their kids can make together. When you’re done, you’ll have a clear, waterproof, rigid plastic Pooh charm that you can use as a keychain, Christmas ornament, part of a hanging mobile, luggage tag, pendant necklace or earrings, or anything else you can think of. invent.
This is what you will need:
A large piece of clear plastic No. 6 (polystyrene)
Fine Point Permanent Marker (Black)
Permanent colored markers (yellow and red for Pooh bear)
Pair of scissors
Headband
Use of the kitchen oven and an oven mitt.
Aluminum foil sheet
Drill
Keychain or rope
First get a large piece of clear plastic n. 6 (polystyrene). This is easily identified by looking for the recycling symbol. A n. 6 in the triangle means you are ready to go. The transparent lids of take-out trays are usually made of plastic n. 6. Next, find a picture of Winnie the Pooh to use offline. Download a suitable photo and print it on your printer on plain paper. Keep in mind that the final product will shrink approximately three to four times smaller than its initial image, so keep this in mind.
Cut the plastic n. 6 so you have a flat sheet slightly larger than the image. Tape the image to the plastic sheet. With the fine-tipped black permanent marker, trace the outline of Pooh, as well as all of his features: eyes, nose, eyebrows, mouth, shirt, etc. Complete his dark features like eyes and nose. Once they have tracked it down, use the yellow marker to fill in his fur and the red marker to fill in his shirt. Then remove the image tape from the paper and cut the plastic into the shape you want (rectangle, oval, etc.)
Move the oven rack all the way down. Place the aluminum foil on the rack.
Heat the oven to 350 degrees. When the oven is ready, place the plastic image on the foil sheet with the oven mitt and close the door.
During the first minute or so, your art will start to curl up and shrink. It’s fun to watch! Then soon after, it should start to flatten out. After about three and a half minutes, your image should be ready. Using the oven mitt, carefully remove the foil pan from the oven.
Your plastic charm is still warm and will stay moldable for another ten seconds or so before it cools down. If it’s not completely flat, you can smooth it out by placing a large, flat object like a book on it. Or if you want, you can fold and shape your art. But work fast before it gets cold.
Once the charm has cooled, drill a small hole in the top for the chain. Attach the chain and you’re done. You just created your own Winnie the Pooh hard plastic keychain! These make great gifts for Winnie the Pooh enthusiasts and can even be used as gifts for baby shower parties.
