Mr. Foster likes to plan ahead. It’s only July, but he’s already wondering what he should wear for Halloween this year.

He thought you guys might be willing to help him out. So here’s your mission from Knit Picks and Mr. F, if you choose to accept it-

1. Create a handmade Halloween costume for Mr. Foster using yarn or fabric. Store bought accessories are okay. You are allowed to base your costume on an existing Mr. Foster ensemble, you can get those patterns here for only $4.99 if you don’t already have them (the monkey pattern is included too).

2. E-mail a photo of your creation to contests@knitpicks.com before August 31st.

3. Help Mr. Foster pick a winner. In early September, we’ll post our favorites, and you can vote for the winner.

4. Check back October 1st when the winner will be announced. We’ll also post a slideshow of all of the entries we received.

The winner will get a special Halloween treat from Knit Picks, no tricks, we promise! <
