The overlapp can be made more pronounced by knitting a couple of extra rows on the main bed. A friend's question hopefully answered.
A slightly overlapping Pintuck is required, I have done somethig similar a few years ago on a golfshirt collar, but this did not overlapp, just stopped the collar ends from curling under. Here is the Test swatch.
Current test for a small overlapp of the pintuck. tan col. swatch at top.
Just for fun, a comparison of 2 old Fern-lace patterns & the different ways they can be programmed &still achieve the same result the swatch shows them knitted in one piece. These patts. can be used as an overall design or just 3-4 repeats for an horizontal edging. There are sooo many various scalloped edgings around, from the small ones to very large ones.
Remember that for Mylars or punchcards, the patt.graphs need to be flipped horizontally.
