Double Detached Buttonhole is simple. On each loop, you do two knots, instead of one. You get what appears to be more of a spacing between each ‘set’ of knots.

The best part of the leaves above is the dark olive green on the left leaf. The outmost light olive green is a bit of a mess – I was working right up against the frame and had a bit of difficulty. I did it twice, with no better results.

The picture is a bit fuzzy – you can’t see the pattern you get across the rows formed by the ridges of knots very well.

The leaf on the left is Double Detached Buttonhole (with no Return)

The leaf on the right is Double Detached Buttonhole with Metal Return (which covers Double Detached Buttonhole with Return as a stitch to be completed).
