WAUKESHA, Wis. (CBS 58) --The National Retail Federation says Americans will spend more than $3 billion dollars on Halloween costumes this year.  So, making your own frightful look for the big day might be the real treat, especially if it can save you some money.  Otto's Art Academy in downtown Waukesha is offering a costume-making class this Saturday afternoon.  It's geared toward kids, and the focus is what's easy and economical.  Organizers stress reusable items, like cardboard and t-shirts, can go a long way when it comes to getting creative.

The costume-making event at Otto's runs from 1 until 3 pm on Saturday.
