I call them simple "rag balls" when they don't have the hook for hanging. Rag balls are a common primitive decoration in the country. As you can simply fill any old bowl with them to add a dash of color here or there.
These are some hand-made Christmas tree rag balls I made.
Price: $4.95 for a set of 5 Ragball bowlfillers (without hooks)
Update: New patterns/colors to choose from in Booth #555. Photos coming soon!
