Hi Ferg,
Thanks for your help! Anyway, those are the one ply linen thread and i am not so sure about the weight. I guess i will get one or two spools of those to try out but i would love to have different weights to work with (imagine sewing with 50/3 for all projects) !
I read that the company was in receivership and was bought over by two young frenchmen, so i thought someone might know where to get these thread in the differing weights. Google churns out only results for the one ply and it is already waxed..
