Yes, probably a stupid question:

I nearly always use a size 70 microtex on my class machine and the tension has always been fine. I switched to a size 90 microtex for a class in paper piecing and the tension needed an adjustment of the dial to improve it.

Does needle size impact tension? Or does the friction of the paper change the tension? I was using the Carol Doak paper.

Thanks.
