Hello Catherine, have you thought of contacting a place like Budget Blinds or 3 day blinds? We have a window that requires a special treatment and I contacted both these companies. Both offer free consultations, their companies offered different solutions, and brought up things I never would have thought of. The cost was more than if I had gone to Ikea and bought some panels, but I am very happy with the end result!

Please post a picture so people can help you troubleshoot the problem.
