Making DIY costumes and bags for Halloween can help save money during the expensive holiday season. One great way to do this is by making costumes with upcycled or recycled materials – this eliminates the expenses involved with buying new items and also the eliminates the chances of running into someone else with the same store-bough costume! TerraCycle, a recycling and upcycling company, has a DIY costume and candy bag that can be created easily from items around the house.
