Pamela, I have an aversion to cutting threads, so I keep a box of 2 1/2" squares next to the machine. Every time I finish a seam, I sew two of the little squares next. I can sew all day and never have to start a seam except when the bobbin runs out. Occasionally, I sew 2 patches into 4 patches, then 16 so they are ready for a quilt.
