So I'm getting around to doing some work on the Irish national. Awhile back I dismantled my SWK Thrifty, so that I could make it fit better. I test pleated knife pleating, and found I could get the reverse and a deep pleat into it only by making the rest of the pleats shallower, and going with a larger reveal. I didn't like it much.

I've decided that I want to go ahead and make it into a box pleat. I tested it, and to pleat to the sett, I end up with 6 1/2" inches between pleats on the outside, and it looks bad. I need some guidance on how to make smaller pleats, while still getting it pleated to the sett- but not so small that I might as well not have pleats at all. I've gone through the search function here, but I'm still stumped.

Could someone come to the rescue here?
