I am making my daughters Halloween costume and she is being Batgirl! I made a tutu onto a crochet top and I have to attach the "batman" symbol to the top, but I'm not sure how! I was planning on sewing it, but how will that work once the top is stretched out? She's 2 so applying it while she is wearing it, isn't really an option because she absolutely won't stay still for me to sew it. I'm stumped! Please help! Thanks in advance!!
