I found some. Well, I think they make a pretty good stand-in. My daughter and I were at the Dollar Tree the other day, and lo and behold, I found: Decorative Container Filler. Did you know they made this? And, if you knew, why did you not tell me? (wink - Truth be told, I was never really looking until now...)
At first, I thought they were tiny wooden balls, but no -- they are actually some kind of foamy product. They are indeed cranberry in color, they vary in size, and have imperfections that make it look as if they have a spot where the stem was.
Thank you, I'll take two bags.
Dollar Tree, people!
