It is helpful. I use the Gutermann for piecing only. I had been told it was the best thread for piecing.
I don't do machine quilting. Not quite there yet. I've only been quilting for 18 months since I retired from teaching. It's a huge learning curve with so much to learn!! However, I've joined the local guild, been going to workshops and learning like crazy!
Still want to learn how to hand quilt. Have the oval frame, understand the concepts, have the needles and thread, now I just need to practice.
