I just did some figuring based on a. queen sized quilt being 60x80 (of course, I realize your quilt may be a little different). The LAer I use charges 0.0275 per square inch. So based on 60x80= 4800 sq. inches x 0.0275 = $132.
For a simple meander, I'd say you got ripped off. Did she at least buy you dinner first?? (Sorry - -- couldn't help it)
