In Harry Potter, house-elves like Dobby get the short end of the stick. However, they’re still fun to cosplay and the ensemble can be simple. You really only need ears, a dingy outfit, and a sock to carry around. Instructables user Kiteman put together an easy to follow tutorial on making house-elf ears from felt, a headband, glue, and a template (which is available for download). You could definitely opt to use a material like latex to get closer to the look seen in the films, but you don’t have to be exact. Whatever method works best for you is completely fine.
Here’s how he reinforced the ears to make them less floppy:
Depending on the thickness of your felt and the clagginess of your glue, the ears may be floppier than you like.
I had bought pipe-cleaners, intending to glue them up inside the fokded toos of the ears, but the combination of felt and PVA proved stiff enough for my needs.
If your ears need reinforcing, trim or fold the the pipe cleaners to the right length to hide inside the top of the ears, and then glue them in place.
Fluffy pipe-cleaners can be fixed in with most fabric glues, but if you’re using smooth wire, you may need to use hot-glue, or some other slightly more heavy-duty glue.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
