DIY Yip Yip Costume Tutorial (Yip yip yip yip, uh huh, uh huh)

These guys were some of my favorites from my Sesame Street watching days.  Call them martians, aliens, Yip-Yips, whatever.  A while ago I saw these guys done up as Halloween costumes on Martha Stewart dot com.  I immediately fell in love with the idea of these as costumes for me and my husband.  I figured talking my 7 y.o. son and 5 y.o. daughter would be futile, so I didn't even try.  However, after watching the video several times, they became enamored by the Yip-Yips and wanted to dress up as them for Halloween, too.  So, 13 yards of fleece fabric and several foam eyeballs later, I had all of the stuff for 4 DIY Yip Yip costumes.  Average approx. cost per costume is $25. 

A couple of days ago I began making one of the costumes.  Surprisingly, I finished the first one in a couple of hours.  I used a Yip-Yip costume tutorial I found at

DIY Yip Yip Costume

I downloaded the child and adult patterns.  The instructions were descriptive and simple enough, but I would not recommend for a novice sewer.  While I am no sewing pro, I have worked with patterns before so I was able to make little adjustments here-and-there so the costume would fit my daughter.   Now that I have made one, making the other three should be fairly straight forward.

The biggest change I made was adding Velcro to the top of the mouth.  While you can see through the black knit fabric during the day or in a well-lit room, it does dim and blur your vision a bit.  I figured this would be (1) dangerous at night and (2) likely to cause a headache after a while.   Though not as cute, it sure beats tripping up concrete steps or stepping off a curb. I also cut slits in the side of the costume so, that when needed, we could use our hands. 
Stay tuned for the Yip Yip family photo!

Happy Halloween!
