It's exciting to dress your toddler or preschooler up for Halloween. It's even better when you don't have to bust your budget. Make an inexpensive costume at home by cobbling together a crayon costume. It's relatively simple to make a crayon in your child's favorite color -- even if you have artistic skills that range from zilch to none. A quick trip to the craft or fabric store to grab some felt in your tot's current fave gets you started on this colorful and easy-to-make costume.
