If you use staples instead of oins like me, turn stapler bottom plate so staple turn out not in. Bye doing this they pull straight out just like a pin would. You will also need to set the presser foot tension on machine very light for silnylon or it will distort the seam. At least thats how it is on my 1927 Singer 99. Perhaps new machines are diferent? Just dont start making skirts , and we wont make fun of you!
