A collection of items to decorate Grandma's house, including Grandpa's chair. Nobody else can sit in it!
I've discovered that if you save an object's specific recolor, that recolor is the one saved to the thumbnail in a collection. It also becomes auto-selected when the object is taken from the collection. So the objects are colored in the collection as you see them here, for quick and easy placement if you like the colors. :)
Remember- you CAN use collections that contain items you don't have. You just won't see those items in the list.
