Shortening the width of roller blinds
We have been given some great block out roller blinds but they are too wide for the window area. Does anyone know if there is a service to shorten roller blinds width wise?? I have tried Accent and a couple of other blind companies but they won't do it because we didn't get the blinds from them. Or can you DIY with the right tools? Husband is a mechanical engineer so handy with the tools - we just need to know where to start and if they can be shortened in width once they are already made?
Thanks:)
