I used a variegated thread for most of the quilt, but switched to a tone on tone yellow for two of the borders. Here I had finished quilting most of the quilt, but needed to go back and add a little more in the green and white border.
The whole quilt. At 62 x 62, it's a little too big for me to photograph on my design wall, but you get the idea.
A closer view of one corner. The two outer borders are such busy fabrics that the stitching barely shows. I knew that would happen, so I did a loopy, swirly design for texture.
