Jannie, it doesn't matter, whatever you want the final outcome to be. If you want a quilt out of a main fabric, like red roses, send that to everyone. They might put red and white with it or only white....All you blocks would come back with the roses, but each block would be a different pattern or co-ordinating color. If you want it all different, then you can send it out that way. You can also state in a little note your preferences. Like on the Boom we are just finishing up, for my fabric in one of the groups I asked that they do not use red. Hope this will help you, love to see you join us, we need new people and different ideas.
