I use couching a lot both in hand and Machine embroidery.
The thread I have used to couch down the fibers is the new Royal Shiraz from the Opulent Collection from The Thread Studio.
I have used Madeira Carat in 2 rows and a green felted wool thread also from The Thread Studio and a variegated silk thread of which the origin is unknown.
In the first row from the left I have used Cross stitch and French knots as the couching stitch- next is Herringbone stitch then Feather stitch and lastly Buttonhole stitch.
I could have added more but I have run out of time as I am taking off for few day break early in the morning.
I will miss my blogging but I won't be near a computer at all while I am away-- but I do hope to come back with lots of photos..
