Use the colors you like. DOn't worry about it being the same as the instructors. Someone commented that one of their LQS says you have to buy your fabric for the class at their shop. I wouldn't be taking any classes there unless then the class was free. I rarely buy all of my fabric for a quilt all in one shop. I like a big variety. I also like to pull from my stash. It is in my stash because I love it, I usually need some things to go with it. Can't wait to see the completed quilt.
