How to felt a sweater.

Fill a bucket with hot water and add detergent.
The hot water temperature is roughly 40 degrees Celsius.(104 degrees Fahrenheit)

In the hot water, wash a sweater with a brush.
The point is "entangling" wool fibers.
To entangle the fibers, move the sweater with a brush on washboard in hot water, not scratch the surface of the sweater.

If your hands feel a little shrinkage whole of the sweater, go to next steps.
The time it takes to make felt affected from yarn density, yarn quality, weave and types of fiber.

Next step is rinsing in hot water 2 or 3 times in the bucket and last rinsing in cold water.
Last step is dehydration and drying.
(On this occasion, the sweater shrank by 30% width, 20% height.)
Eco-friendly felt making.

Thank you!

You should pick up a sweater that's at least 95% animal fiber with a little synthetic or 100% wool sweater.
Wool, alpaca, cashmere, angora-goat hair, mohair, or a blend of these.
Cotton, rayon, acrylic, or other synthetics will never felt.
