If I found a box like yours I would just sew them all together. A friend gave me a box of 1 1/2” squares. I sewed them all together and put a border on. It is small- about 18” square. I backed it with muslin and quilted and bound it and it is hanging on my wall and I like looking at it. Other times I try to go with “controlled scrappy” depending on what I have to work with.
