We loved our wedding at Sinking Springs and would recommend it to other low-key couples looking for a gorgeous garden or barn venue. It may not be a good choice for a couple with rigid ideas about what they want. This is a small farm so you'll need to be flexible and do a lot of the set up/clean up yourself. It is an incredible value.
The farm and barn are simply gorgeous. Pictures hardly do them justice (it's definitely worth a visit). The barn has old farm machinery hanging on the walls, pixie lights wrapped around the exposed beams, a barrel to use as a cake table, and other nice touches. The farm provides endless settings for pictures (a lake, a cornfield, forests, flower beds, a gazebo, a swing).
Ann (the owner) did our flowers with minimal input from us and they generally turned out beautifully. The bridal bouquet was not quite as well done as the other flowers and required a little work, but it turned out fine and looked great in pictures. We would not have been able to afford a professional florist so having Ann do them was great for us.
The 3-star rating for "responsiveness" is because Ann does not use email, so everything must be done over the phone. But Ann is awesome at getting back to you if she misses your call, she is very flexible and can do just about anything you want. You have access to the venue all week so it's convenient for decorating and storage. The venue also has lots of decorations that you can use for free, including things like signs to put out on the road, baskets, flowers, even a ring-bearer's pillow. This kind of stuff comes in handy during last-minute planning.
A warning about summer weddings--it gets very hot and sticky in the barn. May be hard for older guests.
Overall we were very happy with Sinking Springs and would recommend it to anyone willing to put in a little extra time and effort. In addition to finding an affordable, lovely place to get married, you'll be supporting a local, family-run farm.
