Elijah always comes up to me and asks me to tie his blanket around his neck so he can have a cape and pretends to be a super hero, so I have been wanting to make him a cape for awhile now, I just haven't gotten around to it. Luckily though, my sister-in-law threw her son a really cute and fun superhero/Batman party and the kids were invited to dress up too. We just moved so I don't have access to my sewing machine right now but I wanted to make the kids' costumes. Since capes are easy to make and pretty much just a bunch of straight lines, I bought heat and bond hem tape and it worked like a charm. I hand sewed on their logos to the back of their capes and onto a shirt for Elijah. Elijah LOVES his new cape and mask. He has so much fun dressing up in his costume and loves being a superhero. He's such my super little guy!
