Pattern and fabric together, already coordinated. Someone else has picked the prints, checked they work next to each other, and cut the yardage to what the pattern actually needs — so you skip the part where you're standing in front of a wall of reds trying to decide whether two of them fight. Open it and start cutting.
Kits include the fabric for the quilt top and usually the binding; backing and batting are typically separate, so check what's listed on each product page before ordering. Give yourself ten to fourteen weeks for a full-size quilt — starting now puts you comfortably ahead of Christmas, and we carry the thread and batting to finish it.
