All of the above. I've never made a quilt solely from one line of fabric, but I often buy two from the same collection and then mix in what ever I like with it, with no regard for the manufacturer or collection. I might add from my stash, which means it could older (more mature?) fabric or it could be something else I bought at the same time in the store. That's the beauty of quilting - you can do it any way you want!
