Has anyone done this? The stair runner I wanted originally is apparently only available via pictures on instagram & pintrest so im going to go for a plain one and put frim it with a flanged btaid after install. And I've seen people laying stair runners themselves and they look great and easy. But we do have turns on one staircase. What are your top tips - from chosing the type of stair runner ( eg I'm not going to chose stripes because I know I won't get them to match up perfectly). Thank you!
