Thanks for both your replies.....
I'd check the Betaboyz Forum, but I think all supplies of this fabric have dried up. A few people on there do have some for their projects, and might part with a very small piece.
Unfortunately, my powers of persuasion are not great enough to prise the tiniest piece of fabric from anyone!!
Mark - thanks for the South Africa tip, I shall check out possible availability there
Appreciate your help
