Remember the Yip Yip Martians from Sesame Street? Yep yep? Unh huh unh huh? Instructables user sliny shares a pretty easy tutorial for making this costume idea. It’s almost no-sew except for the mouth area where a needle and thread can be used. k7lim also documented a version of the Yip Yip costume on Flickr which makes for a great photo reference.

Below are some more completed DIY Yip Yip costumes for inspiration. Like the first image shows, this makes an easy group costume idea since you just need to choose different color “fur” for everyone.

Here’s a super easy tutorial that can almost instantly create a costume: a fabric mask. No sewing is required for these Carnivale/Mardi Gras style masks, just glue and the embellishments of your choice. Since it’s such a quick and easy project, it would also make a good activity to do with the kids. Maybe a craft idea for a children’s Halloween party?

For a full-face mask, try this tutorial with pictures for a paper mache mask. This method gives you endless possibilities and is more durable than fabric alone.

For inspiration, Faceless Autumn and Deviant Art’s The Mask Club have lots of creative examples.

Craftster user grenouille78 made an amazing costume for Dollar Store Challenge Round 2. The rules are simple: spending $10 or less, make something fabulous and hopefully totally unexpected out of items bought at a dollar store. The entries were all amazing, but grenouille78’s reimagining of the iconic Scarlett O’Hara spring dress is really inspiring. So what was used for this costume?

hula hoop
no-skid kitchen mat
green drawstring laundry bag
package of 200 coffee filters
shamrock garland
2 white tablecloths
package of garden stakes
2 water noodles
—————-
TOTAL COST= $10
