Looks like around $400 for materials and $1200 for labor. Is it a labor of love that you don't really quantify? Kind of like guys working or spending money on vehicles?
Don't forget that you probably need a several thousand $ machine to do it.
My aunt made VERY impressive quilts. Show quality. They're family heirlooms now and besides being on beds, they're hanging on walls. I'd guess her nice ones are valued in the several thousand $ range.
