Had some leftover 1-1/2" squares and created 6" squares with these small ones and now I am trying to create a pattern and need some advice. Also have left over strips and want to somehow put them in the quilt. Pictures show what i have on the design wall and the strips leftover and not sure what color to sew around the squares. I would love to make this a queen quilt but need to add a lot to these existing squares. Any suggestions ?
