A cotton swab solution!
Going over those heavy seams and the presser foot needs support? Don't have a fancy machine with a button to push to provide stability? Take a cotton swab and shove that paper shaft to the foot of the presser foot. Amazing! Turned my struggling machine into one that climbed over six pieces of denim to complete a seam without bending or jamming the needle.
I just had to share. We are a family of short folks. We hem a lot. This is a wonderful discovery for me!!
