The blinds covering the middle window in the bedroom bay have fallen down. Some of the plaster had come away taking the piece of timber they were attached to with them. I've had the wood up there for years to secure the curtain rails to and now the blinds. What I want to know is whats a good approach so that the piece of 1 by 1.5 wont come away again when I attempt to glue it back up as before with no nails and hopefully re-attach the blinds. The area of plaster that has come away is not large. I usually fill with red devil type filler, the soft white stuf which I find easy to use. I need whatever I do to be as secure as possible as I really (and obviously) don't want them coming down again - what would you use / do ?
