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 Yip Yip costumes that I made for the whole family this year.

Awesome hey!? We’re all going to be Yip Yips – from old school Sesame Street!

My original inspiration was from Disney’s Family Fun site. I had intended to make costumes for just the man and I but had enough fabric left over for the kiddos too!

Yip Yip Costumes Supplies

First off, I have tried to make these instructions as clear as possible with free patterns that you can download at the bottom of this post. Please keep in mind that this tutorial was originally written in 2010 with a few updates over the years for clarity.

Supplies for this costume:

** cut into 70″ x 35″ for the top of the costume and for the bottom, three pieces 70″ x 12″, 70″ x 16″ and 70″ x 20″.

How to make a Yip Yip Costume:

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

2. Sew along the dashed lines shown on the pattern, creating the head of the Yip Yip.

The mouth is left open at this point.

3. Cut the tentacles into the three pieces of extra fleece. The tentacles should be left about 4″ from the top of the fabric and 2″ in width.

Hello! Im working on these, but its the first timw for me following a pattern, so if I have a 70×70 I have to fold twixe to get 35×35, is this correct? And where in the pattern will the mouth go? Thank you!

Heya, I’m trying to locate the pattern and it hasn’t come through to my email inc junk! Are you able to send them to me?

Where do I find the printable pattern for the Yip Yip costume?

For some reason, I’m not seeing them. Can they be emailed to me?

Hello, Heather,

Your costume is great ;) Thank you very much for the tutorial ;)

I don’t seem to be able to find the pattern. Can you email it to me please?

Hello I can see a list of materials and 10 steps of instructions but can’t seem to find a pattern as such. If you have a pattern I would so much like it please, I have submitted my details to mailing list and received nothing including junk folder

Can you add me to the workflow as well? I would love to have the pattern. My daughter chose this costume for our Icelandic Halloween coming up in 2 weeks

I would love to get the pattern!
