About a year ago, we laid sheet vinyl in the kitchen. This past weekend we extended that into the neighboring pantry area. The vinyl used to be $3/sf special order, but is now $1/sf in-stock (woo-hoo!).

I had a factory edge at the mate line and assumed that the new stuff would mate perfectly right up to it. Wrong. The pattern isn't continuous left to right, and there are 3 shades of the gray tile. So I found a row of tiles a little bit in that matched up in color sequence, cut a few inches wider, then cut out the rest of the template for the space.

I slid the new underneath the old, lined up the grout lines perfectly, then sliced the new along the factory edge of the old. I then peeled both pieces back, laid down vinyl floor tape, and stuck both pieces to it.

2 problems remain at the seam:
1. The "main" tiles that I had color-matched look ok, but the tiles in the next row over are not all the same color.
2. The new vinyl is a hair thinner than the old vinyl (perhaps why it's now cheaper?).

I don't know of anything I can do about the color mismatch, and I'm ok living with it. But given the differing heights of the vinyl, is crap going to get stuck in there, or will the higher vinyl edge get "dinged?"

One more issue: Because of where we had to line up the color tiles, the factory edge at one end of the pantry came up a bit shy of the floor edge. Due to out-of-square walls and/or flooring, at the far end it's 1" from the baseboard.

A piece of quarter round will cover up the gap on one end, but is short by 1/8" or so on the other end. Any ideas to cover this up? I have extremely low faith that I'll be able to find a color match in the remnant I've got left.
