@.novathehedgehog_0c: For the main part of the arm, add more cardboard if you need to make it longer. Same tape (I used masking tape), cardboard has to be a big piece to be stronger. I used a light clay for the shape over the tape layer, then painted it, spikes were the tutorial before this one. #cosplay #kolossos #sonicexethedisaster #sonicthehedgehog #sonicexe
