I like using panels for quick baby quilts. I usually buy a co-ordinating fabric when I buy the panel, and use it to border the panel (30x42 is just too small even for a baby quilt imho) If the price is right, I'll get enough of the co-ordinating fabric for the backing too. I'll usuall quilt around the objects in the panel picture and then quilt the border in a diamond or piano key shape.
