Here is what you need:
olive soap or soap flakes
plastic to make a resist
First you need to lay out the felt.
Hold the end of the wool roving loosely in one hand and gently pull off a section with your other hand. Hold your four fingers against the pad of your palm, trap the wool there and pull firmly.
Lay out three thin layers of felt. When you start out vertically, the second layer needs to be spread out horizontally and the third one vertically again.
Then place the resist on top of the layed out wool roving.
Then lay out three thin layers of felt - mostly in the middle of the resist. Then fold the felt on the sides over to the middle.
Put some soap flakes into the glass.
If you don’t have soap flakes, you can grate some from a bar of olive oil soap with an old grater.
Pour hot water in the glass and let the soap melt a bit.
Then use the spoon to sprinkle some drops onto the roving.
Press lightly onto the wet roving and make sure that there are no 'holes'. If there are holes, you need to add a bit more roving before rubbing lightly.
Rub genlty onto the wool roving while it is on the bubblewrap. When you feel that the fibers are more attached to each other you can rub the other side and also rub it between your hands.
Then you can take out the resist and rub it some more.
As soon as the fibers are attached, they won't attach
anymore when taking away the resist.
Then rinse the piece in water.
Cut off a tiny part at the top of the felted piece.
Now cover the little lamp with the felted piece. :)
