Easy DIY Superhero Cape

After Buddy watched Superman with his Daddy, he was hooked on flying and wanted a “real” Superhero cape. So I went rummaging through my old t-shirt drawer to find a blue t-shirt to use as fabric.

I didn’t really have a plan when I started cutting. I just cut a cape shape out of the back of the shirt. When I went to cut off the collar, an idea came to me. If I left the collar intact, Buddy could put the cape on and take it off all by himself. And let me tell you, it has been so nice to not hear “Mommy, will you put my cape on?” and “Mommy, will you take my cape off?” all day long. He can put it on and take it off as he pleases. He’s happy. I’m happy. 
So here is a little photo tutorial to show you exactly what I did. (Note: The pictures are of the cape that I made for his girl cousin at his Superhero Birthday Party. Just in case you were wondering why it is purple.)
First, choose a t-shirt on which the collar fits your child loosely and will be almost floor length on him or her. Just to give you a reference, Buddy is 3 and I made his cape out of an adult medium t-shirt.
Lay your t-shirt face down.
Then take something with a straight edge to use as a guide to cut the t-shirt at an angle from collar to corner on each side. Do not cut through the collar, but place your guide about an inch outside of it.
Then open up the t-shirt and cut around the collar on the front side.
And now you have a basic cape that your child can easily put on and take off himself. 
If you want to add a Superman emblem using their initial, follow these easy steps. 
First download this font to your computer. If you are not sure how to do that, click here for directions.
Open up a blank document in Microsoft Word and type in your child’s initial using a capital letter in the Superhero font. Increase the font size as much as you can to make the letter/symbol as big as will fit on one piece of paper. (Note: If you put the letter in a text box, you can make it even bigger.)
Print your letter/symbol and cut out around outer edge and inside detailing to create a stencil. 
Using a Sharpie, trace the outer shape onto a piece of yellow craft felt. Then trace the outer shape and inner detailing onto red craft felt (or hot pink for the girls).
Using a hot glue gun, glue the red/pink felt piece on top of the yellow piece. Shade inner and outer edges of both pieces with a black Sharpie to add definition. 
Center the symbol a few inches below collar and pin in place.
Using red thread and a ball point needle, sew around the outer edge of the symbol.
Tip: When sewing with knit material, it helps to stretch it out a little bit to prevent gathering.
And there you have it. A personalized cape for your little Superhero.
For Buddy’s Superhero Birthday Party, I made a personalized cape for each child instead of doing goody bags. I purchased the t-shirts (royal blue for the boys and purple for the girls) at Goodwill for less than $3 a shirt. 

It only took me a couple hours to make 12 capes and the kids LOVED them, making every minute worth it!
