I've been playing with Aurifil thread over the past few months, and I have to say I really like it. This Italian thread is super-fine, totally lint-free, and is a pleasure for both hand and machine sewing. I've stitched up a ton of samples in all the different weights, and even tried it out on silk.
It's fun to see the difference in the 4 weights of the cotton Mako thread, running from the finest (50) to the heaviest (12). By the way, the weight number assigned to a thread is actually a length measurement: in a 50 weight thread, 50 kilometres weigh one kilogram. In a 12 weight thread, 12 kilometres weigh one kilogram. Therefore, the smaller the number, the thicker the thread. It's the opposite in sewing machine needles, where the smaller the number, the thinner the needle so if you remember that, it's helpful when you are matching needle to thread. A 12 weight (heavy) thread needs a 16 (large) needle.
drop me a line. There will be more colours arriving soon, as well as different weights.
Aren't you glad I asked? :)
