connecting threads, fabric.com, joannes, walmart, hancocks...and many more places sell fabrics for less --- i guess i'm lucky my local quilt shop sells their quilt fabrics for $7.95- $8.95 for batiks.
if you join the
fabshophop
you will have access to over 150 different shops across the country- they all offer different fabrics and there is a vast range of prices.
often shops offering classes do ask you to buy your supplies in their shop- but i have picked up my supply list and shopped where i wanted to many times.
