I've been looking at proper sized scenery items and have repurposed a few from the Lemax range that will look good in the royal garden.
First are these stone benches that look perfect for the King or Queen to take a rest and admire the scenery. This is how they come out of the box, I haven't gotten around to cleaning and painting them yet as I may get a few more and would paint them all in one sitting.

Another, more experimental purchase were the Lemax items seen below. A bird bath and some topiaries.

I did a test piece with one of the topiaries and it came out well, I think. I've since changed the stone colour of the pot slightly to fit in with the stonework on the bird bath (see pics below).
Before and after comparison:

Basically I painted over the snow with green paint, covered it in watered down pva glue and dipped that in a bag of coarse flock and let it sit overnight. Then just a matter of carefully brushing and shaking off most of the excess and let some thin glue dripple over it.
And a picture for size. I think they can make pretty useful scenic items and they really cost peanuts.
Finally, the bird bath. Promotional picture of the original item below, I should stress that they don't look like that in the stores. Casting flaws and shoddy painting (the birds were three dirty coloured blobs on mine) means they need a bit of TLC to get there.

False advertising at work...
After texturing the base to match the K&C figures and patching up any major casting flaws, I decided to ditch the unrealistic red, blue and yellow and try and give the birds a colourfull pattern that could be found in nature too. After some googling, I ended up with this:

I may have overdone it a bit on the birds, as I'm not sure it works.
And for good measure (and indication of size, the King on a stroll in his garden (with a watchful musketeer in the back to keep an eye on him in case the pretty birds get angry)...

Lemax really never ceases to provide useful additions. Where most of the buildings are of a suitable size to use with 28mm figures, the Lemax figures and accessories are in a 60mm scale that is close to that of the 1/30 toy soldier manufacturers. Well done, tacky seasonal decorations manufacturer, well done.
