Below is my backpack that is a Kurgo backpack made specifically to carry a small dog. My dog said no. I put a camera bag insert into the 'pet area' years ago and this became my go to backpack.
I wanted to test out an idea I'd seen a Lego Photographer use when trying to photograph Lego's in a puddle or stream. If you have ever tried it, the boats sink or tip over, the kayaks and canoes don't really float. I've stacked rocks up against Legos in the stream to keep them in place only to back off and get the shot ready...
and the Lego minfig tips over and floats away.
One person suggested hot gluing a piece of metal to the bottom of a Lego minifig stand. I tried that method and it worked well for a while. After bumping around in my backpack and being repositioned several times, the metal washer came off. But it was a fantastic solution and an easy thing to do.
I also took a flat 6 X 6 plate and stood a horse on it. The stream still wanted to pull on the horse, so I put some rocks on the plate to hold it in place. It worked like a charm.
Anyone who has ever ridden horses [or mules] knows that sometimes horses don't like streams or even shy away from puddles.
I imagine that Princess Sara's faithful steed, Ice, wouldn't want to cross the stream. Princess Sara had a tough time convincing Ice that it was OK to go in the water. She even waded into the stream to show him.
Apparently he had none of it until Joan of Knight rode her workhorse into the stream to show Ice that it wouldn't hurt him.
Stay tuned. The Princess and the Knight continued their Quest.
I am just following along.
