First, I marked the locations for two big swoops of echo stitching on the quilt before I loaded up the top. I wanted them at a slight angle to mimic the angles in the blocks. Once I quilted down to the chalk marks, I quilted in a couple lines of echo stitching then went back and filled in pebbles down to the top line.
I then quilted about 6" of echo stitches.
Then continued on with more pebbles.
I found I liked the look of looser quilting on the pebbles. I also liked seeing circles and ovals of all different sizes. The texture was wonderful.
