With the advent of machines where that isn't practical, it appears as though they started making needles with larger eyes such as denim and top stitching/metallic needles.

I did some research and found https://www.aurifil.com/products/aurifil-wool and https://www.fatquartershop.com/aurif...l-12-wt-thread The second link gives some tips to use when using the 12 wt thread with a sewing machine. I'm not absolutely sure, but I think the top stitching needle has a more universal point, but the denim needle has a sharp point. I know that some feel the universal point is "universally good for nothing." I would think that if the denim needle has a large enough eye for the thread to pass smoothly through, it would be a better choice.

I hope this helps, as it looks like the 12 wt thread can be used in the sewing machine.
