I had some of my mobile designs laser cut out of wool felt through Ponoko, a fantastic service that makes laser cutting almost laughably easy. The mobile pieces came out looking great, but there’s two problems.
When you laser cut felt, it smells very strongly like burning hair (go figure), and it leaves a charred halo around the edges. Some people recommend dry cleaning to remove the smell and char, but that was too expensive and environmentally unfriendly for me. I experimented with a couple ways of cleaning the felt, and this is what worked best for me.
Make a mixture of cold water and dish soap
Soak the felt for 15-30 minutes
While still submerged, go around the edges with an electric toothbrush
Rinse with cold water
Pat dry on a tea towel, then leave on the counter to air dry
This method is pretty quick, easy, and works. Just remember to use an old toothbrush head.

As you can see below, the felt will shrink, but it’s not too bad.
