I love handwork. No doubt about it. I use all kinds of threads ..... perle cotton, cotton thread, silk thread, floss, 'whatever I have in my thread box' thread ...... but I really have fallen in love with wool thread. Specifically Aurifil wool thread.
I have just added nine new colors to my website in some lighter Spring-like shades that are just wonderful.
Aurifil wool thread is a blend of 50% wool and 50% acrylic. Acrylic to give it strength and wool just because it is so beautiful.
If you haven't given wool thread a try, maybe now is the time to start! It sews wonderfully whether by hand or machine.
