I will start with the towns...
Intercourse PA - Zooks- lots and lots of fabric
Old Country Store..just up the street from Zooks- again..lots of fabric and great prices
The Amish quilt shop between Intercourse and Bird in Hand- great prices
Weaver's Dry Goods - Brubaker Road - Sheafertown (spelling)
huge selection and great prices, friendly staff.
Martins fabrics - Meyerstown..have a huge table of flat folds for 3.25 a yard and their other fabrics are between 6.25 and 7.20 a yard..again good selection.
These are the ones I go to the most.
Burkholders Fabrics in Denver PA- check their website I think they may have a sale going on and maybe a coupon. They have tons of fabric and notions. The prices are good too.
Sauders (and Zooks are owned by Z and S fabrics) Muddy branch road- lots of fabrics and great prices.
I hope this helps you. Enjoy your trip. Are you spending the night?
