Do you want to make hair mats?

Matter of Trust is currently looking for pilot study partners and we are expanding our satellite hair mat factory program.
We are currently looking for green business entrepreneurs who can felt hair mats and have available free space at their
current location. We have started satellite factories with alpaca, llama, and husky dog rescue centers, who are using this
income to supplement donations to support their charities.

If you are a volunteer looking to make some hair mats in your free time, please look below! 
We appreciate your interest in Matter of Trust.

Do you have space to make hair mats?

If you are interested in connecting to our Clean Wave program, we are seeking 300 satellite partners around the world. Check out our starter kit page and we would love to help you get your satellite factory off the ground!

You will need a free space such as a garage, warehouse, farm shed, workshop… large enough to house an involved operation and away from your living area, as this work can create a hairy situation!

Feel free to contact us by email at or through our Contact form. for more information and the first steps for your satellite!

Looking to volunteer and make hair mats?

If you are a volunteer interested in making hair mats, we are excited to work with you!
You can either felt mats at Matter of Trust’s flagship model factory or at a different satellite factory.

How are our hair mats made?

How we make hair mats…

1. Sort: We start with a framework called a scrim. This uses just the longer strands, 3+ inches, which would ideally have been pre-sorted as such beforehand. If not, step #1 is to sort out the longer 3+ inch strands from the rest.

2. Start Scrim: Lay hair strands out in the feeding tray before the felting machine and space them evenly.

3. Feed Scrim: Start up the felting machine, slowly pushing from the input end while pulling from the output end. This can be done by one pair of hands but works best with more than one person so that less walking back and forth is involved. One person pushes the scrim forward and one person pulls the scrim at the other end at the same time to balance the felting process.

4. Lay Scrim: Once the scrim has passed through the felting machine at least once, lay it out on the intake end again. This time, it is crucial to have the borders of the scrim hanging out over the edges of the intake tray – they’ll be folded over the stuffing.

5. Fill Scrim: Fill in the scrim with shorter hair fibers, stuff them in evenly. Once the scrim is evenly padded with the shorter fibers, fold the portion of the scrim that hangs out over the edges over the stuffing.

6. Lock Scrim: Run the mat-in-progress through the felting machine again, pushing and pulling. Once it’s through and through, it should be reasonably ready for use.

Satellite factories greatly decrease the process’s carbon footprint and create new sustainable jobs. There are so many benefits to making hair mats – through your own operation or volunteering at an existing one. You are promoting local green business 
and engaging with your community on sustainable solutions to global problems!
