Look how lovely- beige commercial grade carpeting that came with the house. So did the stains about halfway up the steps, though I'm sure the kids have left their own marks.
What I found after ripping it out (there's just no chance of refinishing that mess)-
Aaaah. I still get a little charge every time I round the corner to go upstairs and see it in all its stripey glory.
The runners are from Dash and Albert. I ordered two 12' runners to make sure I'd have plenty to work with. The installation started at the bottom of the staircase. The first runner ended on a riser about 2/3 of the way up. The second runner overlaps that one and reached the top stair with about 5 feet to spare. I ran two rows of zig zag stitching where I wanted that one to end, then cut the excess off in the middle of the two rows of stitching. That end was folded under before I put in the final row of staples. I sewed some rug binding tape(looks just like twill tape, but wider and is a deep beige color) to the zig zagged edge of the remnant, folded it under to hide it and ran a straight stitch to hold it in place.
It's the right length for the kitchen. Bonus!
