Needle felted Christmas ornaments are great because they are light and you can fill the tree with them without making it heavy.
The only thing that must be noted, your cat may have extra interest in it because it’s 100% natural lamb wool and the wool scent may give her flashbacks and bring up the urge to kill. Like a yarn ball does.
An angler fish for the geekery Christmas:
If you’ve ever tried needle felting, you know how long process it is, but then you also know how flexible the material is and how awesome it is that you can take a handful of wool and turn it into any shape, a little sculpture or textile. Also, as working space and tools go, you only need a little desk space and one needle.
