You've got a good start. Leave the butterflys off until the end so you can balance your picture as you put them in.... and perhaps leave their wings free. You show a willingness to be bold and that will stand you in good stead. It isn't a photo quit... it's only from a photo, like an artist painting from a photo of her childhood. Ah, I'm old enough to have driven that truck. Makes me miss the ranch where I grew up.
WHAT! your butterflys are PINS??? Well, a butterfly or two never hurt any quilt. :-P
