A question on threads
I have the opportunity to buy a lot of thread in many different colors for a fantastic price. The problem is that its on cardboard cones and looks like smaller cones of serge thread. I don't have a problem with the cones and when tugged the thread doesn't stretch or break. In fact I tried to break it and couldn't. The questions is, do you think this would be suitable for general sewing/piecing?
I looked inside the cones and the ones that had a label I could read didn't have a weight given.
