Halloween help!

So I just visited my friend Circe's blog and realized that Halloween is coming. Crazy I know but in seriously a couple of weeks I will need to figure out all the kids costumes. I need help! I am putting it out in the blogosphere for help with the costumes. Claire has decided she wants to be Scooby Dooby Doo. Honestly I have no idea where that idea came from but she has stuck with the idea for awhile now so I think it is set. The boys are going to be M & M's. Any color I think. I haven't decided.:) I know, not that creative but I haven't been able to find a pattern or baby costumes that would work. Emma...well she hasn't decided yet but I am sure it will involve some fairy wings or princess something or other. I have never made my kids costumes so the buying or borrowing variety works best for us.
There it is. The problem out in the air and hopefully some ideas or solutions. Thanks everyone!
