This ceramic felting stone are a great tool for use in wet felting any flat items or 3 dimensional items.
They fit into the palm of your hand and are great used when you need to agitate the fibres in a certain spot, around the edges or to help attach stubborn fibres like silk and bamboo. I have used it on the shoulders of a garment when it needed extra felting and shaping while on a dress form.
I find that the scalloped shapes are easy to hold, especially if you have small hands.
