How Can I Harden Wool Felt?

This is a question I am often asked.

I prefer not harden the felt items I make, preferring to felt the wool until it can hold the moulded shape I want without having to resort to any glues or hardeners.

However, there are times when Paverpol fabric hardener is extremely useful! I use it to harden lamp shades and bird pods. The downside of using Paverpol is that it goes rock-hard when it is dry. Wool felt which has been hardened loses some of the translucence it naturally has under light. This fact should be borne in mind if you intend to use it to harden lamp shades.

How to Use Paverpol

Paverpol is water-based and is non-toxic. This makes it a good choice for a bird pod, which will be used exclusively outdoors. I use transparent Paverpol but it is also available in a variety of colors.

Note: This product comes with a warning! Paverpol can block up your drainage pipes. To prevent this, periodically clean any containers you use; let the material in the water settle and then pour off the water into a flower pot or the garden.

I tend to use Paverpol straight from the pot, but you can dilute it with water. I prefer to apply it to the inside of on a lampshade with a large brush or knead it into the fabric with my fingers. The bird pod entrance in this case is very small, so I simply paint the hardener on the outside of the pod using a paint brush. I squeeze and knead the woolen fabric well to allow the stiffener to penetrate the fibers. I then shape it and place it on a sheet of bubblewrap to dry.

Projects should be stuffed with a balloon or plastic bags and then left to dry. The bags can easily be extracted but don't use paper as it will stick to the glue. if any of the Paverpol drips onto the bubblewrap, you can collect the excess and paint it back onto the project before leaving it to dry.

Things You Will Need

  • Paverpol/Transparent textile/fabric hardener (500g) which comes in a variety of colors. It can be used to drape and harden fabric or sculptures which will be used outdoors. I purchased mine from Amazon.
  • A template which can be made from underfloor laminate, cut to whatever shape you require. The template used in this example measured 51 cm down the centre. The sides measure 49 cm. You can make it as wide as you like.
  • Merino wool fibers for all three layers. I used up a lot of left over fibers from different projects.
  • A piece of silk fabric (I used a used an old silk scarf) alternatively you can leave it out and make 3 layers of merino wool fibers of the same thickness throughout the project.
  • Party Balloons
  • A heavy duty bamboo blind and a tumble dryer (the latter is useful but not essential)
  • Warm soapy water (Olive Oil Soap grated and diluted in water) Olive Oil soap is kind to the hands but dish washing liquid will suffice if you have nothing else.
  • Bubblewrap
  • Warm soapy water.

Layer 4

  • Cover the silk with a very fine layer of merino wool.
  • A thin layer of wool created a ruffled appearance on the bird pod.
  • Wet with cool soapy water.

Please note that if you want the fibers to penetrate the fibers you should only use cool soapy water so that the fibers do not shrink before they are able to migrate into the silk.

Roll the Project inside a Heavy Duty Bamboo Blind

  • Gently roll the project in the blind.
  • Increase the pressure after a while and keep on changing the direction in which you roll the pod by turning the project inside the blind.
  • Roll until the edges of the template begin to curl.

Change the Direction of the Roll

  • Place the pod in different positions so that the pod can be shrunk from different directions.
  • Roll until the fibers no longer move.
  • You will start to see the template buckling as the fibers shrink.
Keep on changing the direction in which you roll.

Shrink in the Tumble Drier

  • I always opt to use the tumble dryer method for the final shrinking stage.
  • This is an optional step.
  • You may prefer to rinse the project it in hot and cold water to shrink it more.
  • I sometimes take the project out to a hard outside wall and hit those parts which I want to shrink more.

Rinse and Cut the Hole

  • Rinse the project in hot and then cold water.
  • Remove most of the water by giving it one last squeeze or put it back in the tumble dryer.
  • Mark a small hole as shown and cut out very carefully.

Do not make this hole too big, it is much better to make it small and enlarge it later. One is aiming to make this hole the right size for the particular type of bird you hope to entice into this accommodation.

Shape the Bird Pod

  • Shape the bird pod by inserting a balloon into the small hole.
  • Blow it up, knot it and put it back into the tumble dryer until it shrinks to the desired size.
  • Alternatively blow the balloon up inside the bird pod and shape as desired.
Rinse the bird pod well and then insert a ballon.

Paint with Pavepol

  • Use a paintbrush to cover the surface of the bird pod with fabric hardener.
  • The pod should be damp but not wet when you do this.
  • If it is too wet it will dilute the glue and run out more than it should.
  • No harm will be done if you do this though, simply scoop up the excess and paint it back when it starts to dry.
  • Squeeze the project using your fingers until the Paverpol blends so well that it cannot be seen.

Shape the Pod

  • Shape the Pod
  • Start by increasing the size of the hole but don't make it too big.
  • Fold in the sides if you are using a similar shape template to this one.
  • If you make the template pear shaped you won't need to do this step.
  • Massage the cut edges of the entrance of the pod with Paverpol hardener.
  • Put a balloon inside the pod and leave it to dry on a sheet of bubblewrap.
  • If the Paverpol drips onto the bubblewrap, collect the excess and repaint using a paintbrush.
  • The bird pod will dry rock hard making it much more durable in hot and very cold weather.

Thank for stopping by Nell. I am glad you have learned something from my hubs. This is a fascinating medium to work with. Felting is not an exact science and the result is always so unique. No two projects will ever look exactly the same.

Nell Rose from England on August 05, 2020:

That is so clever. I had never even heard of Felted anything until I started to read your hubs. So I have learned so much!

Sally Gulbrandsen (author) from Norfolk on July 16, 2020:

Thank you Devika, glad you like it. Thank you for your continued support, it is much appreciated. Keep safe.

Devika Primic on July 16, 2020:

Wow! Sally you have created a beautiful bird pod and with such determination in each step. I like your work.

Sally Gulbrandsen (author) from Norfolk on July 14, 2020:

Hi Billy, it is always great to see you too. Thank you so much for popping by.

Bill Holland from Olympia, WA on July 14, 2020:

You're speaking Greek to me, Sally, but it's always nice to see your name pop up on my feed. I hope this finds you healthy and happy.

Sally Gulbrandsen (author) from Norfolk on July 14, 2020:

Hi Peggy, no, not yet, as it is a little late in the season but I hope that they will next year:) It might even end up in someone's Xmas stocking. Paverpol is a very interesting substance, it it for instance quite amazing how one can drape textiles to look like real clothing on a wire frame or it can be used to preserve large sculptures which are left out in all weathers.

Peggy Woods from Houston, Texas on July 14, 2020:

What a unique birdhouse you made! I have never even heard of Paverpol textile hardener. Have any birds used your birdhouse yet?
