I'm currently using a 2m wide blind from Ikea as a screen until I redecorate my lounge. It works surprisingly well but following threads from Buns and others comments, I have been thinking about adding black borders in 16:9 format. I thought I might try using black emulsion mixed with dilute PVA. Or flexible smooth black masonry paint, again mixed with dilute PVA. I am hoping that this will make the paint coating flexible enough to cope with rolling the blind up and down. Has anyone tried anything similar and had any success? I suppose if it doesn't work its only £20 for a new screen urm, blind..
