I took my travel sewing machine to a retreat and spent all day yesterday griping at it because it just would not see over the seams in my blocks. I have a quarter inch foot and it was working great but those bulky seams were killing me.
Today, I had a sudden inspiration. Instead of using my quarter inch foot. I put in my regular foot and moved the needle to the right, so that the edge of the foot is a quarter inch from the needle. Viola, a perfect quarter inch seam guide, plus, the fabric I'm feeding through now covers BOTH feed dogs. What a difference that made! The fabric stays straight, it glides over the bulk at the seams, and I still have that perfect scant quarter inch I need.
