I live in N.E. Ohio and here is a list of prices from a local quilt shoppe.
Crib 45x60=2700 sq in for $50.00
Twin 72x90= 6480 sq in for $98.60
dbl/full 81x96 =7776 sq in for $108.32
qn 90x108=9720 sq in for $122.90
king 120x120=14400 sq in for $158.00
hope this gives you some perspective and a starting point
edited to add their flyer states that these prices are for general "meandering". Batting, backing, and binding are extra
