What kind of fiber is the thread? Is it cotton, polyester, mixed,silk, or rayon? If it's rayon, I really have trouble using it to FMQ. I perservered because like you, I loved the varigated colour but it wasn't fun. Visit the superior thread site to see if changing the needle size will help. You may want to try different bobbin thread as well. I just did FMQ with Aurufil cotton in the bobbin and I really like it.
