As described in the New Tips & Tools book, making a small bowl is easy if you use a Baby Gertie Ball. I start off with cold, soapy water (just like nuno felting) with my Weed Sprayer because it makes handling the first 15-20 minutes of shaping the fibers around the ball so much easier -------- if you use hot water (the usual routine when making all-felt) you have less time to make sure you have an even layer of fibers around the shape. Using cold water means you can usually add dry fibers to "bald" spots and experience the kind of flexibility you need to get a nice, even, viable felted shape at the end.
Making shapes is not my forte so I have to work hard to get good results.
This lovely Finnish Wool felted about 4x faster than Icelandic. Because it felts so fast, you can also make either very thin or as thick as you want--------the thinner I can get it, the better.
