Thanks for the many suggestions. Looks like a trip to Hobby Lobby or Michaels is in order. Come to think of it you can buy a 50 cent piece of foam and get a coupon for 40% off the next day from Michaels. If I want some the more expensive markers this might be a good option for saving a buck.

Will have to look at the colors more closely in the Sharpie pack than my quick look.
