I LOVE this!! This is a special quilt, if possivle, I would send it to a long armer, but simple quilting so the houses tell the story.
I think a long arm quilter is the best way to go for a quilt that size! =D
All the effort to make all those friggin houses! Holy crap! I would long arm it fo sho. Probably because I wouldn't trust myself not to mess it up. Good luck either way you choose!-k
For me it would have to be a long armer because I am useless at quilting! But if you are feeling confident then go for it x
