I sometimes have a recipient in mind when I make a quilt, other times as I see it going together I determine that it "just looks like it should be for . . ." And still other times I want one for a specific purpose and look through my UFO and WIP stack and decide that a particular top is just right for that recipient. For me it is a combination of factors based largely on knowing the person ( or situation) and intuition mixed with availability. Some people have to wait for their turn to get a quilt because "the right one " for them just hasn't happened yet.
