I haven't posted for a while, life seems to have taken over from sewing which is always a little scary!!!
Anyway, I don't know about other people but I think there is a dearth of information from interfacing manufacturers with products available in the UK, masses for the USA but not for here. So I've been doing a hunt and here is a link to the vilene product information.

As and when I find other information I'll post it!
