Window Treatments

Window Treatments

Hey everyone. We are moving into a house that has no window treatments. The landlord provides all the tension rods and we have to provide the coverings. I looked at Ikea and their Roman blinds would be perfect but their blinds are only 24" wide and our windows average 29". We're looking at having to cover 16 windows. I can't afford to buy 15 window treatments that I may never have to use again so can you guys please give me any and all recommendations for doing it as cost effective as possible. Just remember, I can only use tension rods.
