I need to get rid of the perpetually dirty off-white area rug in my LR. It's a very small upstairs area (split level home) so the rugs are very close. If I buy new rugs for under the DR and LR table, which area should get a pattern And which a solid? I'm afraid a dark solid in the LR will be too heavy but it's high traffic and I can't keep cleaning a light carpet. Or do I look for matching patterns? Thank you!
