Kathy commented that she should be writing down the ideas. No need to make notes, these pictures are posted for you, Kathy.
This first quilt is a rail fence miniature. As long as the curves or arcs are gentle, they can be accomplished quite nicely with a walking foot and there is no need to drop the feed dogs and wrestle with controlling the stitch length and moving the quilt at a steady speed while stitching in free motion.
This quilt was marked with a blue marking pen using the edge of a glass to make the arcs across two strips.
This picture shows the closeup of the stitching on the blocks.
This is the back of the same quilt. The scallop design on the border was accomplished with a stencil. Again the curve is gentle and easily accomplished with the walking foot.The secondary design was not intentional and has the appearance of the apple core block.
The alternate squares in this miniature nine patch were stitched to look like the nine patch blocks--simple straight lines.
I love it when a secondary design that wasn't part of the original quilt plan emerges in my quilts. When I finished this log cabin quilt and showed it to my husband he declared that he could find the surprise in my quilt--the birds. This quilt was a simple two colour log cabin and there was no intention on my part to arrange the blocks to form four birds in the four corners of the quilt. Further to that, without realizing it, my quilting accentuated the bird image.
Simple parallel lines at an consistent angle finish off the border.
This is my favorite technique for a narrow sashing or border--a serpentine stitch. This stitch is a modified zig zag type stitch on my Bernina.
