I need some advice on making my seams invisible. My seam doesn’t 'look' bad, but I can feel it. It feels like one side is higher than the other, but I measured the leather prior to installing and am confident that it was uniform the entire length. I’m using a Wrap Magic to make the longitudinal cut and have only done two wraps (on the same cue). I’m using the cutting template that came with the fixture and my tops and bottoms look great. I think I’m keeping my razor blade completely vertical, but I may be wrong. I’m wondering if a slight undercut would be better. Any suggestions?
