I had several pre-cut practice squares that a lady gave me some time ago. I have been putting them together. I also tried using the same color scheme to make additonal blocks. I am wanting to put these together as a lap quilt. I want to use the quilt as you go method that was shared on this board. I know it is kind of scrappy but that is okay with me. I just need to know what color or print to use for the backing since it will also be showing on the front as a sashing. Please help with suggestions.
