But let me share fun, cheap and easy alternatives. Go home grown and green in the process. Even if your kiddos are obsessed with the current Sprout hero/heroine, there are ways to create excellent, one of a kind costumes that will scare the neighbors and your kids when they think back - boo!
Here are a few:
Cowgirl/boy - what you'll need: rope and hanger for a lasso (no 6 shooters here), traditional hat (make one of out of construction paper or brown felt if you don't have one), bandana or red/blue scarf, blue jeans, checked or other shirt. And if you like to sew or glue gun things consider an easy vest or chaps. Yeehaw!!
Ghost - white pillow case - standard, queen or king size (for tall gobblins) - cut head and arm holes, if you like.
Jack o lantern - orange fabric for a hat/hood, black clothing - top and bottom, drama wax to black out top and bottom front teeth, a smiling gobblin
Working woman - dress her up in an old suit and don't forget the attache for candy handling. You could really rock the neighbors world with some rimless glasses and an updo - a la you know who Ms. Palin.
Get the picture? Fun, fun-ee, cheap, easy, gives you a few extra hours back from planning, driving, buying, etc. And it's all green.
Just watch for sugar shock.
