Looks awesome!!!!
One other thing you might try is a tear away stabilizer underneath. It really helps. I usually buy the Pellon brand as it's generally less expensive but any brand will work. When you're done and tearing away the stabilizer -- hold on to the block close to where your tearing and gently tear. Another great thing to use is the tear away/wash away -- which means the first time the quilt is washed, all the excess stabilizer on the back will dissolve and be gone! :D
