A comment about the 1/4"quilting foot -
verify that it actually is 1/4 inch - some are "off" by a bit -
Rulers can - eventually get worn -
Change your rotary cutter blade when it gets dull. Use appropriate sewing machine needles for your project - and change them when they get dull. When you hear thunk, thunk, thunk - as you stitch - it is time to change your needle.
Read the instruction manual that came with your machine.
