Shereen is right - every rug is unique. Maybe this is your start to an illness, many poeple who are active on this forum share :-)! The rug virus is very dangerous. If you start collecting, rugs will enrich your life, but sometimes it will also make you mad.
Comming back to your rugs.
I recommend you should have them washed by an expert, and have the defects fixed. You will enjoy these rugs for many years, and maybe these where not the last ones to come in your house.
