Tartan: The one closest to the lights, I would definitely use as a light. The three in the center, I probably would not use. They all seem mid-tone to me, which you are not going for in this pattern. Possibly the yellow and the tan. if you are using others that are similar, so that they don't stand out too much against your lights (the lights I can see are very light; just one or two strips that are that dark will look out of place). Not the paisley in the center. The white backround will pop out if it's on the dark side, and the print covers too much of the space to let it be a light. I love the paisley, but this type of fabric is the hardest for me to use, unless it is in a border
