Yesterday I showed some 'process photos' of a white wool on silk scarf with Rusty Orange and Black designs on top of it. Now, if you look at those shots, you can still see all the loose fibers, laying on top of a very fine and open silky fabric.

After this part, the 'laying out', I wet down the fibers (carefully, as to not disturb the design) and start 'irritating' the fibers as much as possible. This is mainly aimed at the wool fibers, that need to open up and start 'grasping' one another. To open up the fibers you can use soap and hot water, although I don't want the felting process to go too fast (as the wool also has to travel through the silk), so I often start with room temperature water and Olive Soap.

Then I roll it all up, again, carefull, at this point it's all loose fibers still, in bubble wrap plastic, as the bubbles will provide extra irritation to the wool.

From then on I roll this bundle of bubble wrap and fiber and silk on my table as often as I can, rolling it out and up again to check on the felting process, until the fibers are felted - ie, you can try to pick up a few fibers but they stick instead of fall out of your felt project.
