I find a lot of lint on my pressure foot when using Essential from Connecting threads BUT I also clean out the bobbin case and foot ect with my brush when changing out every bobbin so really no worries. I am a beginner so I buy whats on sale as long as it's cotton, I started sewing my clothing years back and always used cotton thread so I figure my clothes lasted a long time so will my quilts. I usually use C&C unless I can't find it in the color I want, then it's another brand of cotton.
