This complete soap felting tutorial shows you exactly how to make bar soap covered with wool felt

Why put wool fiber on bars of soap, you ask? Great question! Because it makes a wonderful scrubby. You can exfoliate and wash your skin at the same time.

Not only is this a fun activity for you but it’s a great craft for kids, too. So, let me show you how to make felted soap.

The basic steps for making felted soaps:

Gather supplies: Bar soap, wool roving, nylon hose, water
Thin out the wool and wrap it around a bar of soap
Place wrapped soap in the nylon hose
Add water and work it with your hands
Check the soap occasionally to prevent wool from felting into the hose
Work the soap until wool is firmly felted and attached

What is felted soap?

Felt Soap is literally soap that is enclosed in felted wool. Basically, the wool is placed on a bar of soap and as you work it with water, the fibers felt together.

As you use the soap, the bar shrinks and the felt shrinks with it.

Materials and Tools

Wool Roving (s.a. Sheep or Alpaca)
Bar Soap or Olive Oil Soap (for Gifts!)
Nylon Hose (Knee Highs work well)
Water

How do you make felted soap?

Soap felting can get a little messy since you will be using water. So, before you begin, think about where you will be doing this. You can work the soap over a sink or a large bowl or cover your table with a plastic tablecloth.

This is also a great activity to do outdoors with your kids.

1. Prepare the wool roving

The first thing we have to do is prepare the wool roving. All this means is that we will thin it out.

Simply, take your roving and with your hands, spread it out just enough so you start to see through it. Not too thin, you don’t want gaps in your fiber or the soap will show.

Take a length of wool and wrap the it around the soap, tucking in the ends. Check for any holes in the fiber and add more as needed.

You can use one color of wool or many. You can make stripes or solids … whatever you like.

2. Felt the soap

Now, carefully place your soap inside one of the nylon knee highs. You can easily do this by holding the wool covered soap in one hand and stretching the nylon over it.

You need to be careful not to pull the wool off the soap. No worry if this takes you a few tries! Once it’s in there, secure the stocking with a loose knot.

Then, either over your sink or bowl, add some water and using your hands, gently begin working the water in. Do this all over the soap until the entire surface is thoroughly wet.

Work the wool for several minutes and then carefully pull back the nylon and check for spots where the soap is showing and add more fiber, if needed.

Place the soap back in the nylon and keep working the fiber. Make sure to work all surfaces and the corners.

Remove the soap from the nylon every couple of minutes to check the felting process and to make sure the nylon does not get felted into the wool.

When you can no longer pull apart the individual wool fibers, you can continue working the wool without the nylon.

Keep working the wool until it has shrunk and tightened around the soap. If it seems that your wool doesn’t want to felt, try ‘shocking’ it by alternating hot and cold water while you are working it.

Finally, just rinse off the suds and set your soap out to dry. This may take a day or two. Rotate your soap so the felt can dry on all sides.

3. Add needle felt designs (optional)

With this particular bar of soap, I first needle felted a simple star shape (see how in this tutorial). Then I lightly felted only the white wool onto the soap but only until the fibers were just starting to grab onto each other.

Finally, I added the star on top of the white and finished felting it until the wool completely enclosed the bar and the fibers could not be pulled apart.

How do you use felted wool soap?

Use these soaps the same way as a regular bar. If you have very dirty hands, you can scrub between the fingers and under the nails.

Note: After use, do not let them sit in water. You may wish to hang them up to dry. This will keep any mold from forming.

As I said before, these soaps are great scrubbies. They are wonderful for anybody who gets their hands dirty such as gardeners.

Also, felted soap works great for exfoliating your skin. In that case, you will want to use a higher quality soap such as scented lavender or olive oil soap.

What are the benefits of felted soap?

Natural way to exfoliate your skin (when using natural colored wool and all natural soap)
Great for removing dirt from hands for gardeners, mechanics, etc.
After the soap is used, the leftover wool felt can be composted
Make great gifts

How long does felted soap last?

That really depends on how often you use it as well as how large your initial bar of soap is. As a general rule, one bar will last from about 4 months to as long as a year.
