There are many styles of pleated headings for panels. A flat, tailored style of pleat is known as an inverted pleat or box pleat. It is made by stitching in pleats with the fullness to the reverse side of the heading instead of to the front like with a French or Goblet pleat. I have put together some of my favorite tailored panel styles which all have unique looks but the techniques are very similar. Enjoy!
