Compleated my first knife pleat/Tartan today, except for loops. Man it is difficult to line up stripes on fell. I pressed and pinned before I sewed, if anyone has any pointers on that it would be a big help. My wife picked up the material at Joann's, it is a poly blend. Lets see if it holds better than the cotton I was using. I pressed the pleats on the wood floor, maybe that will help.
