Great ideas thank you! Depending on where you are from you could make them into holiday trees (ie for Christmas) or you could turn them into elegant dolls such as with the angels. You could also use them to shape a new design by inserting it into your stitching instead of using a fibre fill...for say to make a woman's gown fill out and hold it's shape or if you have a smaller one it could hold the shape of a bird's head. You could also make a silly cat or dog sitting, just add a head.
Hope that gives you some other ideas. What you've already shown is just marvelous! Good luck and post pictures of what you come up with :D
I like these cones, they look very decorative but not necessarily Christmas-y. You could mimic the same idea with your existing yarn cones rather than making paper cones. They are from the Creativity Exchange blog if you want to look at more, they have tons of ideas for them.
