Halloween

My mom is coming into town for Halloween this year and we are going to my sister's house to spend it with Nora and Jack.

Nora has decided that she wants to be a sheep this year and we are going to make her outfit. I found a costumes on the internet that we can make, but nothing that I'm crazy about. Any suggestions?

PS - Jack is going to be a skeleton or a lion and we already have his costume.

PPS - In my search for a sheep, I found this ADORABLE chicken costume on Martha Stewart.
