I am not exactly an arts and crafty person, so I was afraid that somehow I would make a mistake in an attempt to use it. I have a longer torso and shorter legs, so many of my pants just hang too low. I wear heels (boots or sandals), but the pants almost always cover them up, & sometimes touch the ground (yuck!). But I needed something simple, and this is it!! I just pinned the hem where I wanted it in regards to the length I was desiring, put this thin, skinny "tape" inside the hem, and ironed as directed...and it worked!! So easy, the only time consuming part (and this was not a long period of time) was deciding on new hem length and putting in the straight pins. I was afraid that doubling up the fabric would make bulges on the bottoms of my pants, but no issue at all! Ordering more--LOVE this item! Great price, THANK YOU!
