Use a larger rawl plug and hammer a smaller one into it?
Trim a piece of wood and hammer in place. Pilot hole. Can't fk that up. Yep, just whittle a piece of softwood down so it's a tapered fit, tap it in & trim off the excess. That's what we did in the days before rawlplugs. ^^^this, or buy wooden dowels for doing the same I've wrapped electrical tape round a rawl plug to get me out of trouble Depends on application of course Thanks everyone for all the suggestions so far. I'm going to try them in order. So matchsticks first. This sounds like the easiest option. If that doesn't work I'll get a bit of 7mm or 8mm dowel, hammer it in, drill pilot hole then screw in (no rawlplug). Failing both of those I'll try a brown rawlplug - though I'm not sure whether I'll need a bigger screw as well - that would be a problem since the picture hook can't take a screw bigger than the one I'm using at present. And if all that fails I'll try Gripfill. Moving the hole isn't an option, since the picture in question has to go in this exact location. Hence the need to "save" the hole. Got any car body filler in the garage, the 2 part epoxy type? If so mix some up and fill the hole then set your raw plug in before it goes off. It'll never come out.
