Si vous voulez avoir les étapes en français, je traduirai, vous n'avez qu'à demander.
Nuno felting is a Japanese fabric felting technique. It melds loose fibres, usually wool, into a sheer fabric such as silk gauze. The Nuno felting process is particularly suitable for fine garment making, since silk-backed felt ensures a stable felt that will not stretch out of shape like normal felt. It also creates a lightweight felt.
In this tutorial, you will also see the process for regular wet felting (without silk gauze) with corriedale wool. This creates a thicker piece, good for belts or thicker scarves or anything else really!
You will need some natural dishwashing detergent (I use Seventh generation), rubber gloves and a watering can with little holes. Some people simply pour the boiling water through a colander.
You will need and old wooden blind or tatami, as well as long pieces of bubble wrap and lots of towels.
Lay the tatami (for smaller/thinner pieces) or the blind (bigger/thicker/longer pieces) on a long table or the floor, lay the bubble wrap on top.
Place your piece of silk chiffon on top of the bubble wrap and trace around it with a marker (I am making a scarflette here).
Then, TAKE THE SILK CHIFFON PIECE AWAY, and place your wool. If you want to make a reversible piece, you will start by putting little tuffs of colored wool or silk here and there (it's time to use your pieces of yarn if you want to add some), then put a layer of merino wool on top.
You want to create a batt, you'll see better in the photos with the green wool further down.
To pull the wool in order to get a nice thin layer of wool, procede this way:
Close your palm on top.
When you have two layers or merino wool (one horizontal and one vertical), put the silk chiffon on top.
And start you next layers (you can do only one if you want a thinner scarf or two for a thicker one).
Then, add your details on top.
Here's another project with more step-by-step photos. This is a belt with corriedale wool (no silk chiffon in the middle).
Carding wool to mix the colors.
Starting the first layer (batt). The fibers go all in the same direction for one layer, then the second layer goes perpendicular. For this belt, my friend did 3 layers, plus the details.
We see the batting process quite clearly here, it's like roof building with wool. Make sure there is no holes.
Starting to add details on top of the 3rd layer.
Then, pour boiling water with a dime of soap. You want the piece to be very wet, almost dripping on the floor.
Cover with more bubble wrap.
And a towel to limit the amount of water on the floor...
Take a pool noodle and roll around it, making sure that everything is nice and straight.
Tie with old nylons so nothing moves...
And roll for a good 10 minutes!
Then, unroll and tuck in the fibers, so you don't have holes around the edges of the final piece.
Before tucking the fibers...
Then, pour some more boiling water, put the bubble wrap and the towel on top (still with the pool noodle and the nylons) and roll another good 5 to 10 minutes. Then, fold your piece in two, then four.
And for 3-4 minutes let it drop, gently at first, then with more and more strength (unfold and fold the other way around so it doesn't felt on itself).
Then, move to the sink, put your rubber gloves on and add more soapy boiling water on your piece, put it in a ball and throw it in the sink many times (you do this for another 5 minutes and until it is felted to your liking, the more you felt, the harder it becomes and the smaller it gets. Don't be afraid to throw it hard at this stage! When it starts to get wrinkly, it's usually felted enough. It really depends on the look you want.).
The finished pieces :
Now, hang them to dry! The colors will change a bit when they dry, especially the silk that becomes shiny.
Please let me know if you need any more photos or information. I'll be happy to make it clearer!
