First take a look at, or indeed join TAST and learn, the stitch at Pintangle. Then you will know what it should look like. Sharon B, our teacher, always produces stitches that are neat and tidy.
My first attempt was on the Aida sampler, where I used a purple linen thread and a pink coton a broder. These types of thread have very little twist and the result is - appalling! Green perle 8 behaved better.
Please note, though, that going down the left side of the 'ladder' base stitches the thread sits neatly whereas working the thread in the different direction, as seen on the right side, the thread WILL twist and misbehave.
On my sampler I switched to a newly acquired hand dyed variegated perle 5,
Even so the movement of the stitch makes the thread curl up and misbehave a bit.
One TAST participant said it was hard to find where to insert the needle for the second knot. Here is how I solved that problem:
Step 1. Make the first Buttonhole loop.
In the end I liked this stitch so much I am now off to play with the next one, #137 Beaded Knotted Buttonhole Bar. My report on that one will be posted later.
