I tried to fit a new Roman blind to the top of a recess. But, couldn't drill terribly far into the top of the recess. Maybe only to 1 inch depth. I was using an ordinary drill not a masonry drill. I hitting the lintel is that what is preventing me drilling deeper?
Alternatively am I drilling the holes for the screws too wide? The blind fell down ☹️
If it is the lintel how do you fit Roman blinds into a recess with top brackets?
