I think the think you're asking about matches the description of
something they sell at Walmart for less than five dollars.  I've heard

other type of tent, you can find a pattern for --one of the major pattern
companies, in the doll accessories section.  And resize, if needed, or
use as-is for a smallish gang of happy campers.
