Review: Sturdy thick thread! - The polyester thread was nice, thick and sturdy - no breakage! It worked great with a heavy duty machine needle (100/18). It required my sewing machine tension set at level 7 which made a lovely zigzag finishing stitch on the perimeter of the fabric I purchased to make a gray waterproof canopy replacement cover for my outdoor swing! Would have liked a gray colored thread but the black thread made a pretty contrast. Was well worth the cost!
Review: Did it's job - Thread color was exactly as it stated it was when I received it. Thread was packaged very nicely and easy to start using. Seems to be heavy duty worked perfectly for the project I was working on. Would purchase it again.
