Does anyone happen to know where I can get cellular blinds similar to the inexpensive ones that Coachmen uses? I want to replace the metal mini blinds in the rear bunk area. They're useless with kids sleeping and playing there as they get bent up and are in the way. I think they're about 20" high and between 24 and 34" wide. The height is the problem because most home cellulars are a minimum of 48" tall.
