Keden7 and her family have always loved the Yip-Yips from "Sesame Street," so when she found some Muppet-like fabric at JoAnn Fabrics, she couldn't resist making these costumes for her kids. The Yip-Yips' eyeballs are made from Styrofoam and the antennae from pipe cleaners. Inside the costumes are foam hats that make the heads a bit pointy and the lips are foam-filled and attached to a stick, so the wearer can move the mouths with ease.

Addiechauvin's 4-year-old twins love Halloween and couldn't wait to wear their homemade Wall-E and whale costumes.

JoelleBurnette transformed her daughter's umbrella into a giant jellyfish using bubble wrap bunched up under a layer of clear plastic wrap, adorned with silk tentacles. Wearing a mask and snorkel, she wound the tentacles around herself, as if she were caught by the sea creature.

When KatrinaLynne's 3-year-old daughter wanted to by syrup for Halloween, she assumed she was in for a difficult and time-consuming project. Once she got started, she was surprised to find that she could create a syrup costume, as well as a companion waffle costume for her son, in just a few days, and for very little money. 

The syrup costume is made from brown felt, yellow fabric, ribbon, and paint, and the top is an empty cookie container painted yellow. For the waffle, KatrinaLynne used a 1-inch foam square, on which she drew the waffle's gridlike pattern and used a craft knife to cut out each 2-by-2-inch square. She used brown marker for the lines and yellow chalk for to color the inside; the syrup on top is made from felt and the butter is foam she colored yellow.

We love the idea of a costume does double duty as a disguise and a candy holder! Bridget350's husband made this costume for their son. It features red and green lights that really light up, and a yellow light in the center that pops out from the inside to capture candy.

Sbatty's son is fascinated with school buses; whenever someone asked him what he was going to be for Halloween, he would respond, "A school-bus driver." She was determined to make the costume for him, and did so with great success -- and without a pattern!

Tiachia is enjoys making humorous costumes. Of her octopus getup, she says, "I put on the costume and drove to work. On the way, a guy cut me off, so I shook a tentacle out the window at him. He nearly crashed! At my desk, I was the most efficient employee ever, all eight legs typing, filing, and poking my coworkers in the ears!"

Tiachia shared this photo of her niece, Ellie, dressed as a tiny shrimp.

Quillenriver's daughter Amanda wanted to be a Mini Cooper for Halloween, so her dad got to work and built this costume out of foam core board. Here she is, "parked" on a New York City street.

Lehuie entered this photo of Emma dressed as a bag of groceries. The milk carton, loaf of bread, and all the fruit and vegetables are made from felt, and the bag itself is made from fleece reinforced with craft foam sheets.

Brendase513 shared this photo of a monster-truck costume made from boxes, tape, and paint attached to the little trick-or-treater with suspenders. While it was designed for Halloween, the kids enjoyed the truck long after the holiday.

When Alex, 3, decided he wanted to be a rocket for Halloween, JANAMES's sister Julie Allen was able to design one for him. JANAMES considers herself to be very fortunate to have such a talented sister, as she was unable to find a premade rocket costume for her son.
