I received my order from Keepsake Quilting. I ordered what their catalog said was 50 weight-3ply thread.
What I got was 30 weight thread machine quilting and craft thread. That's what it says on the thread label.

Can I machine piece with 30 weight thread? What difference will it make--good or bad?

I feel like sending it back but don't want to spend the $ for returning--it was their error or mirepresented in their catalog.
