Activity for Ashley

Here are some pics of our venue. It's on the lake and we'll have about 30 guests. I'm going for simple and intimate. Inexpensive would also be nice, but I'm not sure how exactly to budget for flowers for this or if I can DIY. Besides a bouquet for me...

I think I finally found the ring! 1.5 ct tw from Helzberg's. Opinions! How long did everyone shop for their rings? Show off the rings!
