I didn't realise that it was that nice, I thought it was just plain like the axminster stuff. I have no idea what to use the 34mm stuff for.
I am not sure what the outside diameter of the roman harvest would be the frill size is 13mm. so you may get away with the 18mm stuff, You are welcome to a couple of pieces if you want.
I have just phone Anne at GPS Agencies - Real ivory alternative and replica materials and they sell 1.5metres of 20mm for £16.90 + vat and delivery of £12, but if they cut it into 4 then they can send it by royal mail which would be cheaper. They will cut it into any lengths you want and charge 5% for cutting.
