Thanks everyone for the kind words about my quilt. Carol, yours looks lovely and I too like the wider border.
Audsgirl, I used a favorite method to get the double sided skinny border. After I sashed the blocks together and did the same width as the sashing around the top, I layered the quilt and quilted it. Then I "grew" it by adding the skinny border (red on the front and pink on the back), inserting the batting for this border and then doing a single stitch line through that sandwich to secure the batting within the border. I did opposite sides and then the other two sides. After that I repeated the process with the wider border of the feature fabric front and back. This is a quilt-as-you-go technique I learned online somewhere. Before the additional borders, the quilt was less than 42" wide so this method allowed me to back it with a piece of my feature fabric that was not pieced. Additionally, quilting was easier on my DSM than it would have been if I waited to sandwich and quilt until the top was completely pieced. This method also allows wonderfully precise pieced back and front borders.
