For the border of the Pickle Dish and Mariner's compass quilt, I designed the pieces to fit around just one pickle and then seam them where they met. I remembered a cool technique that I learned from Judy Niemeyer on how to piece large pieces together in an ice cream cone fashion.
Here is a picture of my freezer paper template of the border piece.
I marked the seam lines and a few key intersection points and left a bit of overhang on the outside edge to be trimmed after the quilt gets quilted.
It's quite easy to sew this long curved line this way, by letting the curved piece stay curved on the bed of the sewing machine.
When it was all sewn, the seam was pressed towards the outside edge and away from the pickle dish unit.
I hope these pictures and description of the steps helps you on your next quilt.
