Even when taking photos in my backyard on my picnic table, I will camouflage the bases of the stands with some sand the same colour as the wood of the table....as I did here.....
Can you see the doll's bases?
then hide the base with small matching stones....
(pants aren't that straight), and there's also a bit of base showing in front of one of his shoes.
Here's another photo with the doll's stands hidden with snow.....
So why not give it a try?
