Here's a case of 'losing my marbles'. And nuno felting with a bit of silk gauze I had snow dyed earlier this year when we actually got some snow. Both sides are attractive and the wool and silk roving adhered nicely.
For this one I tried adding some velvet devore strips, silk scraps and sari threads to the wool and silk roving, but I ended up covering the goodies too thickly for them to show much - oops!
And dry felting on some embroidered tulle first, followed by wet felting.
The more I experiment, the more I see how sewing and the various types of felting and materials could work together.
