Don't give up!
Measure your panel.
If it is not an easy size to work with, add a simple border to make it an easy size to work with.
Pick any quilt block you like in whatever size you need to make another round around it.
Add another simple border around your pieced blocks. Ta-da! It's a quilt.
Here is a picture of one that uses 3 simple borders instead of any pieced borders.
