Step 1: Get your materials together
A pipe cleaner
A felting surface (like ribbed shelf liner)
Really hot water
Step 2: Wind up the wool
Step 3: Wet felting step
Now you are going to actually do the wet felting...get your soapy hot water ready!
The microscope photo is of a single wool fiber. I wanted you to be able to see what is going on when you dunk that wool in the hot soapy water. See those scales on the fiber? They are the cuticle of the fiber. Your hair has a cuticle too, it acts like shingles on a roof, protecting the hair or in this case, wool of the sheep. When you put the fiber in the hot soapy water, the cuticle scales open up and grab onto one another, and as they cool, they close, tightening the bond. Doing this repeatedly, along with agitiation which smashes the fibers together, is what creates felt.
(I'm a bio teacher, btw, so that is where I took the photo, gotta love it when school and art come together)
Step 4: Shaping the wet felt curl
Now you are going to take your felt from being a boring bit of felt around a wire, to a dynamic curl shape. You could shape this in other ways of course, that is up to you.
