Last year, my two older kids were Egyptians and I could NOT think of how to make a baby Egyptian costume! Instead he was a mummy.
This is just how I made the kids' costumes this year. I think I spent about $15 on both of them. I had a ton of muslin I used instead of sheets, tea dyed everything, ripped and sewed my brains out! A GREAT idea I found somewhere, was to also tea dye a pair of white tube socks. When they went trick or treating, we put them OVER their shoes, it looked GREAT!
