Superheroes seen in comic books often have unrealistic proportions. Women are given big chests, and men get giant muscles. Though it’s not necessary to match a character’s physique when you cosplay, you can add bulk if you want to. Instructables user spiderball built a Thor costume for Halloween, and he used craft foam to build up his arms to Norse-god like proportions:
I wanted my arms to have a bit more size so with the 1/8th [inch] craft foam I cut segments to create the muscle groups of the arm. These groups were then hot glued together giving me a fake arm which started at the top of my shoulder down to the wrist.
This was trial and error to get the size and shape you want. I started with a bicep to get the scale for the rest of the arm. The first picture is of the shoulder, I placed it over my actual shoulder and moved around to make sure I had enough room. The next picture is from the shoulder to elbow, once again I slipped it on to make sure it was to scale and I could move in it.
Once both arms were constructed I coated them in contact cement and then placed on a layer of cheese cloth. This gives strength to the seams to prevent tearing. Next I cut out 3/4″ squares and covered the arms from shoulder to mid forearm, the squares are craft foam and hot glued on.
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.
