Great, just ironed on with pant leg inside out and sticky part facing area to be patched (I put a piece of brown paper bag between pant leg so it doesn't don't stick to other side of leg) Don't use steam on your iron and heat it on maximum setting. I then pull leg back through correctly and iron on sticky side a little (not much) I just hit it a few times to be sure it is set! Oh and when you cut the patch, ROUND the edges. PoIntel edges are prone to peeling back more. There grear and heavy duty patches so glad I found. Men's work jeans like carhart are expensive and reg carpenter jeans knees blow out fast! Lifesaver!!
