i did a wool appliqued bom quilt one year-- the patterns alone was $60--i think it wasn't quite as expensive as that one but still pretty high- when i finished it i had it appraised- its appraisal value was $3700...and that was 5 years ago- prices have gone up (for materials) since then so i can see it costing that much now- the thing about bom's is it does distribute the cost over several months so you don't have to come up with it all at once; sometimes that alone makes it worth it.
