After working a few more variations, I completed this up and down buttonhole stitch sampler of this week.
The sampler-

28.up&down b.hole stitch-sampler2

The details ā€“
15. the first row is the combination of up and down buttonhole stitch and cable stitch, in the second row, French knots are worked in between the stitches.


16. in the first row, detached chain in two shades are worked between the stitches and in the second row, detached fly stitches are worked between the stitches.


17.these rows were worked too closely to take pictures of individual rows. The details-
First row, this stitch is worked with herringbone stitch.
The second row, a variation of Cretan stitch and up and down buttonhole stitch are worked together.
In the third row, bugle beads are added and in the fourth row, pearl beads are added to a row of this stitch.


I enjoyed working these variations, though while detailing, the name of the stitch was too long for me use it repeatedly!
