I have a pair of jeans I want to alter. I don't know if this can be done, but I am willing to give it a shot. What I want to do is take in the outside of the thigh and possibly the seat to "unrelax" them. I want to taper to about a 1" or so removal on the widest (relatively) part of the thigh, to as-is at the knee or so. My question is, is there anything I need to watch out for? Do I need a special type of thread for this, for example, cotton so it will shrink some and pucker the seam a bit? The current seam is not felled, so it shouldn't be that hard to blend it in. Also, how should I go about trying to match the fading along the edge of the outseam? Sandpaper, dilute bleach...? Am I just crazy? This is my 'favorite' pair of jeans, but that's not saying much at all. Thanks.
