I so so so badly want to do capes and masks this year. I think it's such a fun idea to be able to give the kids something like this at the beginning of the party so they can all play superheros in the backyard together.
Check out these masks!
While we won't have those exact ones, we've sourced out mask sets locally at a party supply store ($.99 for each fabric eye mask!) and the capes will be handmade, but simple. Just basic cotton fabric rectangles with velcro closures. Easy peasy, but coordinated with the theme and fun for the kids!
