The two things this instructor said we had to do was always use the same sewing machine for each top and we were to use bobbin thread. Was this just her quirk or is there a logical reason for this?
It DOES make a difference. Even the 1/4" foot on the same TYPE of machine (i.e. Pfaff 2170) will be different enough to make your seams a bit off. You don't have to specifically use bobbin thread, but don't change the type of thread throught the project. If you're making a block that you need to trim to size, this isn't so much of an issue. But better to be safe!
