Hey guys! Are you possibly as excited for Halloween as I am??!?!? The boys’ Birthday is October 26th which totally adds to the fun factor! Check out these costumes that I made for the whole family:

Awesome hey!? We’re all going to be Yip Yips {from old school Sesame Street}. Check out the video:
My original inspiration was from Disney’s Family Fun site. I had intended to make costumes for just the hubs and I but had enough fabric left over for the kiddos too!

Yip Yip Costumes {and FREE pattern}

First off I have tried to make these instructions as clear as possible with a million photos {I have a happy trigger finger – what can I say?} and the free patterns that you can download; for the child sized pattern click here, for the adult sized pattern (part 1) click here and for the adult sized pattern (part 2) click here. Please email me if you get stuck anywhere along the way.

Lets gather our goods ~ a 90″x90″ fleece blanket, a roll of cotton batting, 2′ of black (see through) material, 2 4″ Styrofoam balls, 4 1/2″ Styrofoam balls, 2 3″ Styrofoam balls, 8 pipe cleaners, black paint, paint brush, pins, coordinating thread, hot glue gun and sewing machine. (With these supplies you can create two costumes. One adult and one child sized.)

Cut your fabric as shown in the pattern. Start with the body and pin the right sides together.

Sew along the dashed lines shown on the pattern.

Here’s what the adult size will look like turned right side out. For the child sized costume you will simply cut tentacles rather than attach them to the bottom.

    My computer flaked on me so if I post 2 comments I didn’t mean to. But these are adorable and you did a fabulous job! I had said you should post pics of all of y’all together for us to see. =0)

    I’ve been wondering what I could wear this year to our Oncology Floor Halloween party. We have lots of little kids, so I don’t want to scare anyone. Perhaps a YipYip would be the answer?! Now I only need to convince my geeky husband to hook me up with a video of them for my candy bag – in case the little ones aren’t as Old School.

    Be proud! You did a wonderful job on the costumes.

    These were my favorite characters when I was little, but it seems very few people actually remember them lol! I’m so glad to have found this, it’s definitely going in my halloween costume ideas folder. Thanks so much for sharing!

    Uh-huh, Uh-huh, yip-yip-yip-yip (lol)

    Ummmmm…..that is THE CUTEST, MOST AWESOMEST costume in all the land!! I adore Sesame Street, and this was just soo much coolness, I had to stop by and say a HUGE cyber high-five to you! Really. I’m kind of getting emotional about how much I love this. You rule!

    Yip Yip costume: I think I did the lip wrong. Was I supposed to leave a few inches of mouth fabric around the edge when I was sewing in the black mouth? I don’t understand where/how I’m supposed to put the batting to make the lip, as the black fabric is sewn right to the edge of the fleece. Please help.

  10. KATHY says

    I hope you still remember how to make your Yip Yip costume. I am a great fan of them also. I’ve always wanted to make them for Halloween. I’m 70 and there couldn’t be a better time to try. I understand most of your instructions. I haven’ t cut anything yet I just can’t follow where the mouth will go. I think once it is cut out and sewnI will see it more clearly. Is that a seam down the front? Would appreciate anyhelp you can give me.
    Thank you,
    The outfit will be for me.

    Hi, Heather! Thank you for the tutorial! I am having problems with the lip of the mouth. I saw on the other comments that you put batting on the inside and pull fabric to mouth seam. I am having trouble pinning stretched enough where the mouth looks pronounced. My question is do you have any other tips and tricks for lips. Any help would be much appreciated. Thank you!

  12. Chris says

    I’m a complete novice at this and I’m having trouble following this tutorial. I have a lot of questions; please bear with me. 🙂

    I’m looking at the pattern in pdf format, and rotated the image to where your handwritten “1 of 2” is in the upper left hand corner.

    – Where is the “head,” “mouth,” and “front” from the photo in the tutorial in relation to your drawing/pattern?
    – The way I get the 35″x 35″ dimension is if I fold the fabric twice; giving me four layers (single folding will give me 35″ x 70″). Am I supposed to fold the fabric/blanket twice? If so, what is your “sew” line referencing? Am I supposed to sew through all 4 layers?

    I don’t see a seam down the front in the photos with the finished product.

    I appreciate any help. Thanks.
