I managed to miss the Up&down buttonhole on the first TAST challenge.I got caught here. Initially thought this was a hard stitch,but later found this was not so.

this sampler is also on checked fabric, I had some gingham cloth left over from stitch explorer challenge, chicken scratch.

I tried the stitch in ,2, 4,and 6 strands,then did a 3-step feather stitch.

I extended the 2nd stitch on this row.

Varied the width alternatively.

Made the second stitch shorter than the first.

Did the stitch in 2 colours.

In this row, I went down twice[LOL].

Going down twice, added some bugle beads too.

Laced with thread ,

made this stitch in 4 steps[is this the right way of saying this?]

Now thought, How can I use this stitch on closed feather stitch?

Another variation of- Up& down closed feather stitch, quite a handful is n’t it?[because I am typing]

Mixture of closed feather stitch and up&down feather stitch, with beads too.

 Here I added arrowhead st on top and bottom.

this one is with detached chain

Stitched beads at different points on this row.

Three rows of this stitch,This could have been used for up&down buttonhole stitch too.
