Hi Jonas, Many thanks for this complete answer - and very useful advises. Indeed, given this article (in French), they say the "early century machines (including the 45K) should be able to work with a 2,5-3mm yarn". But, that means - yes - finding size 300 needles, and I had not considered that it would cost that much. https://maxandshed.wordpress.com/2020/12/23/une-singer-45k-par-mscr/ In top of that, I have checked with French historical supplier (of linen thread) and their thickest quality is a 1,2mm - so, quite not the 3mm I have been considering at first. The idea of sweing the thread with another thread can work, but I am not sure that the tension of the linen yarn will correct in this case. I think I will consider two options for now : . Hand sewing with a thick yarn (3-4mm). . Working with a 1,2mm thread, and here maybe the job can be done on a regular heavy-duty machine? I will make some trials! Many thanks again for these good words. Clément

Hi everyone, I'm starting to think about a project that consists of sewing wool fabric (approx. 400gsm) with thick linen thread (diameter: 3mm). The aim is to use linen for decorative purposes but also to avoid synthetics. Given the thick diameter of the thread, I'm considering using an industrial leather machine. I have read quite a lot of advice by @Wizcrafts, particuarly on the following post: I would love your opinion on what you would recommend: Is an industrial machine (like the Singer 45K) recommended, or is it "too much"? My main challenge is finding a machine able to "accept" a 3mm or 4mm diameter thread, so I don't know if I should consider only heavy-duty leather machinery or if other options are possible. If the 45K or equivalent is too much, what "more gentle" option would you recommend? Would you recommend waxing the thread, specifically for sewing wool fabric? Many thanks for your advice, Clément
