We found these online while searching for options, but $40.00 - $50.00 was too much for something my son will outgrow in a year. He liked the simple version without the belt but wanted the mask and cape. The belted one was a bit too loud for his taste.
this is the link for the simple version. for some reason I cannot hyperlink it.
Step 1: Head to the Thrift Shop
Zip up hoodie = $1.99
Donor sweatshirt = $.99
Next run home and begin.
Step 2: The Tear Down
Step 3: Cape
Step 4: Patterns
Pattern #1: The Bat.
Print out a Batman logo of your preference (in this case traditional) and make sure it's sized to fit. Cut the pattern out and fold it in half. Once the pattern is ready, lay it on an area of the donor sweatshirt without a hem and trace it using either a white crayon, chalk, or tailor's chalk. If you have a non zip hoodie trace the whole shape. If you want the zip up style, trace each half together or separate and make sure you end up with two halves of the logo.
For the zip up style, we'll be using one half on each side of the zipper.
Pattern #2: The Cowl
Draw out the cowl pattern and curve the top so it matches the curve of the hood. You may have to give this one a try or two to make sure you have the eyes and nose in the right place. I recommend test fitting the pattern before transferring and cutting. Once you are happy with the pattern, transfer it to the fabric and cut it out.
Step 5: Accents
For the forearm spikes, you will need three for each side. These can be cut from the un-hemmed fabric. Fold one side in and stitch it. Fold the other side over this part so the unfinished part matches the fold from the previous part. Add a stitch here as well. Once you have that, sew a stitch across the bottom and repeat five more times.
Step 6: Assembly
Assemble your hoodie in any order. I began by sewing the mask into the hood. Once that was complete, I attached the ears to the outside keeping in mind they should be higher on the head so they stand up. Next were the arm spikes. These were attached at the seam. (you could also separate the sleeve seam and sew them in). I chose to leave them outside since the sleeve color and the spikes matched. the cape should be sewn across the shoulders or at least at two points. Last was the bat logo. I left a little space so as not to interfere with the zipper. They can always be sewn closer, or you could opt for a heat transfer print. Now it's complete and functional.
