I also live nearby, and agree with all the other comments. One more place to stop on Route 23 is the Goodville Fabric Outlet. It's on the opposite side of the street from Obie's, and about 1 block west. They have a sign on the roadside. Also, in an email from Sauders:
"Sauder's Fabrics, brick and mortar store, located in Denver, PA is having a storewide 20% off sale starting March 6th and running through March 15th. (closed Sun. March 9th) In addition, we are opening up our warehouse for our quarterly bolt sale. where you will find special low prices on full bolts (no additional discount applies)
The last time I went, the bolts were $3.50/yd., but you must buy the whole bolt, usually 10 to 15 yards. Great for backings!
