I used one of my quilting rulers to help me space out the pleats evenly. After putting in the first pleat, I layed the ruler along the pleat line, then pulled fabric back over the ruler to the 2 inch mark. I pleated the length of the fabric, pinning and then machine basting the pleats in place.
Next I pinned the skirt to the top portion of the slipcover and sewed into place sewing right up against the piping. This was much easier than I expected; everthing fit very nicely
I left an opeing so I could meet the end of the skirt in the proper place.
