Tammy from Dollar Store Dollhouse wrote in a comment about painting the bottle brush trees. My paint selection is rather limited so I stuck to white and green. The color of most of the trees was not to my liking so these were subjected to a bit of dry brushing. Huge improvement. Sorry my photos are not very good but they do look really nice. Take a look at Tammy's tutorial on using easter egg dye to recolor them.
Here is a photo of the beaded tree I picked up by auction last year. Truth be told it is my second. My original is in storage and the goal was to use this one to learn about lighting with fiber optics.
