I like to use only 'trusted' brand threads.
My hard efforts must stay on the fabric too, after laundering too.
I had a bright orange thread run on my baby quilt before.
Buy the best thread you can, is my "motto"
From Bev

I have quite a few spools of QA thread. Have been using it since about 2003, and towels, sheets and pillow slips I embroidered in 03 and 04 have been washed regularly and the colours are still beautiful and none of them have run. The only thing I have noticed about it is that sometimes it seems to unravel a little on the end when I am threading the needle but that is easily dealt with.
Cheers, Bev.

I have only used Threadart and now Metro with no problems.

This was the first embroidery thread I bought when I got my machine. I have a Brother and no matter what adjustments I made to the machine, it still hated this thread - it snagged or snapped so many times I wanted to throw my machine out the window. I went back to the dealer & she spent a couple of hours trying out different brands of thread to see what my machine liked, sadly Q&A didn't turn out to be one of them. Spotlight had all the sets including variegated so I was pretty disappointed I can't use it. :) xXx

My brothers hate it too. xx

I use QA thread in my Janomes 300E and 11000se - no problem. They are really cheap as well and do have lots of shades in their colours.
