Rasant is a great basic brand for a poly cotton wrapped in cotton all purpose thread. This is the thread I favour when I need just black, which is most of my quilting time. 50wt, 1000m spool.
So far on my “Monster” quilt I have used 4000m of this thread. That is 4 kms of quilting so far and I am quite exhausted!
Black thread is often a requirement for my classes so now you can purchase it from me to add to your must-have Helen Godden painting and quilting supplies!
