Here's a photo of the pond with the beach. The beach rock is just drain rock, mostly about 1-2 inches around, then pea gravel as well. If you make it slope down into the deep water, you'll have to somehow place large rocks to keep the smaller rocks and gravel from sliding down. I used mortar, but it didn't really work well at all. Now I'm wishing I had made more of a ledge and used really heavy rocks on the edge of it to keep the smaller ones from falling down into the deep water.
The 'heavy layer' I referred to is probably a double layer of drain rock. But I'm thinking more about using some larger rocks further down to keep the drain rock in place. The ones I have mortared onto the liner are not stable at all. Franny has taken to plunging into the pond a couple of times a day. I simply have to make it where she can do that without my getting anxious about it. Doggy toenails and my expensive liner do not mix!

Also, regarding how big: the bigger the better! I've never known anyone who wanted a 'smaller' pond than they had. My pond ended up being about 5 times bigger than I originally planned, but I love it and am glad it's so large. I had no idea of all the cool plants I could grow in a pond!
