I usually buy the fabric that jumps out at me and says, "Take me home, I'm the one!" When that happens I usually buy 2-3 yds and if there are coordinating fabrics that I like I get them right away too because with my luck they will be gone when I go looking again. That being said, I rarely pay full price for fabric. I have found great fabric online through many of my favorite sources. I also buy the Quilt of the Month collections from Walmart. I have found very nice fabric at Hancock Fabrics, Hobby Lobby and Jo-Ann Fabrics as well and always wait for a sale or coupon. Of course if I were taking a road trip to Lancaster or anywhere else I would definitely check out as many quilt shops/fabric stores as possible, especially if my DH was offering. In fact I would have it all mapped out in advance if possible :) I hope you get to take your trip soon!!!
