The rugs were delivered rolled up therefore it took at least 2 weeks until they would lay semi flat but they still had large creases.  I used books & other heavy items to try & get the creases out to no avail.  I finally took my portable steamer & steamed the rugs flat on a very low setting & this took a long time but the rugs look much better.
The rugs are slippery so need to get non slip backing.
