Ok, so I originally posted this in the wrong forum- oops! Let's try this again...

I've had my TPE mat for about a year and a half now, and I've noticed that it's becoming stretchy. When I'm in postures like downward dog, warrior I/II, triangle, etc., the mat stretches between my "anchor points". Granted, the TPE has always felt a bit elastic to me, but this is becoming disconcerting and distracting...

I haven't practiced yoga long enough to know if I've worn out a mat, but Google tells me that stretching is a sign of wear. Experienced practicioners, would you replace it? If so, with what?

Many thanks in advance!
