Moss Mounds On Clearance at Jo-Ann's

I was at my local Jo-Ann's craft & fabric store over the Labor Day weekend, and was pleasantly surprised to find these really neat "Moss Mounds" on clearance. There were two kinds; large ones that are approximately 7 inches in diameter by 6 inches in height, and were priced at $2.97 each, and smaller ones that were approximately 3 to 4 inches across that were priced at .50 cents each.
These will be very useful for my Venus project. I'm not sure if I want to leave them as is, or add some bits of foliage to them to give them a little visual interest. Perhaps I will use them as Parrotmen burial mounds and add a few small flowers to them. One of the downsides of them is that you cannot easily stand figures on them without them sliding off. So, adding some foliage might make some nice anchors to catch figure bases on, so as to help solve this problem.
They are shown with 25mm Kroot 'parrotman' for scale.
