Phew.... that was a real stretch of my creative muscle.I trustfully started adding the treads, but what a task! I used masking tape to fasten them and a needle to weave them together, one by one. Below is a close up on how it looked when all the weaving were done.
Next thing was to glue it all down to the open spaces, I used matte medium for that job. When completely dry I used an excacto knife to cut all the treads. Only ones left is in the open spaces. See photo below.
The next one is a close up of the finished piece. I used twinks, Egyptian gold, to suggest the gold threads in the more solid parts of the top "fabric".
And finally, the finished piece. It isn't what I initially had in mind, but I'm very pleased with my result. I won't give up on trying to make the surface I wanted, but right now I need to do something quite different.
