Going with the Grain

Okay, now I have worked with wood most of my life so I understand what the phrase "going with the grain" means, however, today I learned a new area that it applies to also, rugs. While vaccuuming the area rugs in my favorite retreat in Whitefish I figured out that it works much better if you "go with the grain" of the rug, otherwise the vaccuum tends to suck it up and pull it along with you...crazy huh, who ever thought that the rugs we walk on every day have a grain to them. :) Just a tidbit that I will have to remember someday when I have a house big enough for area rugs.
