Look no further than your closets and bookshelves. Many ideas are right in front of you and can be made fairly easily with a few things in your kitchen drawers or closets. For example, if you have youngsters, you likely have books about fairy tales or Disney picture books for inspiration. Without much of a creative streak, you can help your kids look like Shrek, Fiona, Luke Skywalker or Princess Leia. With some dark, round frames, you’ve got an instant Harry Potter. Pinterest is a great go-to spot to find eye-catching and simple costumes. And, if you do buy materials or some clothing you don’t foresee using again, be sure to donate to www.ClothingDonations.org.
