Quilting....

So as you have seen I am attempting to quilt, I have really enjoyed it so far. I have even put together another quilt top this time using the Attic window block. It is race theme for my son. I was curious to know if you ever have the perfect fabric but dont want to cut into it? I feel like if I cut it I might mess it up and it makes me nervous to work with any of my "pretty" fabric. Well thought I would see what you guys thought, heres a pic of the newer quilt not quilted yet.

(Sorry the pic isnt the best, this was with my phone, theres a lot of cars and flames lol)
