You could quilt the dotted lines and also tie it. The dotted lines leaves alot of open spaces to tie;it would fit the time period. I'd find a blue close to what's in the quilt or the green since they are the dominent colors for the border and then do a prairie points for the outside instead of binding or do the scallop edges to accent the trees. I like your fabric and think it'll be pretty. Hope you show a picture when you figure out what you are doing.
