I have made wet felted wool balls before multiple times but this time I decided to try and needle felt it. I loved it! Even though it is much more time consuming the result is more sturdy and you can make any design on it (I have needle felted designs on wet felted balls before but unless you needle felt the whole ball the area with the design will be noticeably denser). I tried one with a bell and another without. The bell, obviously, made poking needles in it more difficult, so next time I try it I will wet felt the core with the bell inside and then needle felt the colored rowing on top. I suspect if you use magic wool instead of rowing you get a more uniform appearance (with rowing you see that all fibers go in one direction) but it is much more expensive, so I am saving mine for wool pictures. If you know where to get magic wool cheaper than $3.5 per oz, let me know, I would appreciate it!
