I drew the design onto a piece of curtain lining and sandwiched the lining and the satin together in the embroidery hoop. Flipping the hoop backwards and forwards I could follow the design drawn on the backing.
I tried two different stitches. My first choice, couching, didn't work too well (see RHS of picture). This involves stitching over the cord at regular intervals. Because the cord is an inner cord covered fairly loosely with a satin weave tube, I ended up with a sausage effect, little dents very time I stitched over. This wasn't what I wanted at all!
I then tried stitching through the cord, and was much happier with the results. I need to do a little more experimentation to see if I can find a way pf producing neat, sharp corners. Sharp turns are key feature of this design, and at the moment the cord spreads on the internal angle - probably one of those noone but the seamstress would notice, but the whole point of this project si to make itas perfect as possible :)
Finally, just to make you all jealous here are a couple of picks of where i was when I sewed this.
