For those who've been following this I know it's been awhile since I've put anything out about it. Technical difficulties have greatly inhibited progress and Murphy's Law seems to have been rampant through this process as I'm sure you've ascertained. The biggest update so far is a determination that estimating size with the Jacquard technique in Tunisian is problematic and far from exact. So we're settling on design elements more and exact dimensions less. I know that with the dimensions estimated that the cloth will be greater (thus far in width) than the estimated original dimensions so it's not too small which is good - so it serves it's purpose if not altogether how it was originally conceived.
Funny how art has a mind of it's own...much like a living being it becomes what it will become your plants be damned!
