Oh Sharon
I do feel for you try not to get too worked up about it. I was going to suggest using a larger Denim needle too. Other than that I don't have any idea other than maybe taking it slowly when you get to where the seam blocks meet.:wink:
I am sorry I have no other advice, I sew with a Pffaff & have no problems what so ever, good luck & remember don't fret now.
