Dear Cygnus, I can give you more than a ballpark figure for the pro-colour surcharges. I am having two of my registered designs woven right now by Scotweb and each pro-colour is 150 British pounds (approx. $230.00 U.S.). Their minimum order is 10 metres of fabric, or equivalent in tartan products. Coincidentally, the pro-colour I chose was "Mango-Tango" the same as Mindrop used here! Nice design, Mindrop, and I, too, like the narrower white stripe better. Please talk to Nick - you'll find he will be very reasonable and accommodating. ***Amble******
