Beryl here, I love to needle felt but don't do it the traditional way with wool roving, I use fabric with a design on it. At the moment I'm playing with a satin Chinese-type fabric, the colors and designs are so beautiful.
I lay the fabric on felt and using the Embellishing machine work from the front and then from the back. I love the distorted surface design it creates which also has a wooly effect.
Once I have a few different sheets of these I just cut into them and start layering them into a desired design. The next stage is to embroider and bead to my hearts desire, sometimes knowing when to stop is the problem.
So now I have an image which has come about by adding tyvek motifs and fabric paper panels, beads and brads. This panel is one of seven which will become a book (I think.)
