This is what I'd been hearing, but there's no other way of doing it. The house is slightly below the road and the gap between them is at least a couple of metres. So using the roller on its own attached to the end of a pole won't give me any control over the design. I suppose I could get in close to the wall if I used a ladder, but then getting away would be harder.
So like I say, if anyone who's done anything similar before can give me any tips on best techniques to avoid ending up with something messy I'd appreciate it. I've made a frame for the stencil to make it easier to manage and someone else will be holding this up for me, yeah also with poles - I know it's crazy - but what else can I do? I can't see myself having more than 5 mins to get it done.
I think your ethics & mine don't look alike. For me, if a stencil belongs somewhere, I'm not going to forget it just because someone will have to clean it up.
