For Halloween this year he wanted to be Stupendous Man, which is Calvin's superhero alter-ego in the strip.
I was excited about his choice this year because 1) it was awesome, and 2) it was super easy. The costume consists of the following:
- Hobbes Doll - Optional. You can make one with the pattern I've included in my Hobbes Doll instructable linked above.
- Red shirt with black stripes
- Black pants
- Red Cape
- Superhero cowl - Use my child-sized superhero cowl pattern. If you need a bigger one, follow my instructions in step 3 to make a cowl pattern for adults and especially fat-headed children.
Step 1: Calvin's shirt and pants
I purchased a new red t-shirt for my son for about $3. Using a black permanent marker and a ruler I drew lines on the shirt every 2 inches on the front, back, and sleeves.
We had some black pants that he wore, although any dark-colored pants would have been fine.
Step 2: Superhero cape
I started with a piece of red cloth, folded in half so the folded dimensions were 18" by 30".
Two tie pieces were made and sewn to the shoulder areas of the cape so it could be tied in place, matching the style of Calvin's cape in the strip.
See the photo notes for all of the dimensions and where to cut, hem, etc.
