I have a gorgeous wool patchwork area rug made of old handmade Turkish rugs stitched together. It appears that the cotton backing was poorly attached to the rug by just stitching the edges together.

I’ve had it for a couple years in my living room and some of the wool has started to buckle/wrinkle. Regrettably I never used a rug pad underneath (I have since ordered one). I’m sure it was caused by furniture shifting/moving around over the years..

Is there anyway to smooth out the buckles & prevent further damage?
