You do not have to sew from raw edge to raw edge when sewing on the machine. Many 1/4" feet have quarter inch marks on them so you can stop 1/4" from the raw edge. Take a couple of back stitches at the beginning and end of each seam because you will not be sewing over previous seams as you piece the block. Learned to do this the hard way.

After a few more blocks, my methods of matching and pinning for machine sewing are improving. The templates have a midpoint, but the ends took a few tries to find the "sweet spot" for perfect alignment. With less handling, the blocks press out into a better square. Yeah! Now I can save my handwork for quilting.

I bought the Curvemaster presser foot at a quilt show years ago. It makes curved piecing so easy! Watch the YouTube video on it.
