so you can keep the flow of the pattern, it traps the over lap down that you've wrapped around by the small amount.~The reason you don't go around teh corner in one go, is if you did it like thatthe corner stretches once the paste/paper dries out and because of the tight tention across the corner, it makes it 'caravan up' - ie: form a bubble on the internal corner. So it'sbest to measure the distance, best to do Top, Middle and Bottom, to see if the corner runs out at any part of it. trim it at the widest measurment... allow 5mm or 1/4" wrap around. Then re plumb.. hand the next lenths as shown. If the corner is running out... hang it to the corner at teh shortest width of teh paper... and any excess paper wrapping back across the corner needs to be trimmed off. BUT.. always make sure the re hung lenth is plumb.... if teh corner is out, you can't do anything about it.
@@ProfessionalPainterDecorator Thanks! I got it done, pretty much exactly as you described and very happy with the result, though it took several days!
