JoAnn's had t-shirts on sale, 3 for $10. I had a 40% coupon and purchased a pack of glitter glue (red, gold, silver) for $6. I drew a crest on paper for each of my kids and traced them on the shirts. Then I filled in my tracing with the glitter glue. So for $16 and about an hour of my time, my little superheroes have extra special shirts to wear to the party! And they become part of the decor too!
Not bad for about $5 a shirt!
