These rugs are so pretty and soft.  They are not very thick.  But, the  cotton design gives it more of a 3-D flower look.  The non-slip on the back is kind of a wax coating.  I'm not sure if it will come off when washed.  Hope not.  I purchased the dark red and it's really stunning.   It matched the wallpaper and the accents for my bathroom perfectly.  I only needed 3 rugs, so I'm saving the 4th as a spare in case one  gets worn out or something is spilled on it accidentally and it gets stained.
