I was thinking this morning about what my favourite thread is. Much of the time I think this depends a lot on the purpose for which you want it. Different types of threads are suitable for different projects.
For me, perle thread is probably my all time favourite thread. That’s because it has a nice shine, is a non-divisible thread, and is available in a range of weights and colours. Of course I like using it for Hardanger, but also Portuguese whitework, and freestyle embroidery. If you give me a choice between perle thread and stranded floss in the same colour scheme, I’ll choose the perle version over the stranded floss version any day.
Another favourite of mine would have to be Stitches and Spice’s single ply silk. I just love its shine and the appearance of reeled silk. Naomi, who dyes this thread, has a lovely range of colours, and I love the fact that they have slight variation of tone (and sometimes colour) along the thread. It makes a lovely effect when stitching. When stitching with this thread, you can twist it for a different effect than you get if you make sure it lays completely flat (and not twisted). It means that you can get a range of effects.I also do like DMC’s Color Variations threads. They have a great range of colours. And Cosmo Seasons have lovely colours, at a great price.
I recently received a set of Dinky Dyes silks. They are gorgeous, but I have yet to explore them properly. I just haven’t had time (what a surprise!) but I am looking forward to doing this in the future.
They’re some of the threads I like to use. What threads do you love, and why?

I’m becoming seriously addicted to silk threads since I started doing Tricia’s Historical Embroidery courses. I find the flat silk difficult to manage, still, but the stranded silk thread is wonderful, and easy to use!
Anything variegated gets my vote as well…
