You can always add them as 'art' to the backing of a quilt.

Add more solid blocks and make a larger quilt or maybe you can turn it into a table topper

Take the middle square to the bottom right hand side and put a solid square in the middle then use sashing and boards. Now you have a lap quilt. Let us know what you decide!

Do you have anything to coordinate if so use 4 as a center X and use the other 4 as off-set corners or as corners

Do you have anything to coordinate if so use 4 as a center X and use the other 4 as off-set corners or as corners

Can you wait until you are doing a quilt of similar colours and use them in your outer borders as corner squares and middle squares?

These blocks turned out beautifully and the 4 together look really nice. You've been given many great ideas already, but what about looking for a spring panel that has different printed sections to it, an using the 4 in the cent as main focus, then the remaining 4 in the corner with the panel sections and maybe some other blocks &/or solids or marbles (I love Moda Marbles!) to make a twin quilt or wall hanging. Really great work! Patty

maybe you could use 4 of them for the center and build around the four blocks and use the other for in corners with a cordinating color

If you have enough to make the missing corner block, I think you should and use the design you have going now.That looks neat and gives you a great looking design.

Decide on an alternare block, a nine patch variation, find fabrics that coordinate with the ones in the blocks you have now and make what you need to finish a quilt top.
