This is a soft felt, 10mm thick, with hessian scrim in the centre. It's like a really nice 100% wool underlay. It's a versatile material suitable for a range of applications. It would be great to use in rug backings or felt art.
You can use it as pure wool underlay but be warned, it's only 50% moth proof as it's made from 50% ionic protect wool and 50% clean-but-untreated Herdwick wool. If you've tried our Snug Feet insoles, you'll know how great it is to walk around on pure wool. It's got a natural bounce and springiness about it. If you want 100% mothproof underlay we advise you to buy our Silentwool that is entirely made using Ionic Protect.
Wool is sustainable so it's better for the environment than synthetic materials used for most felts. Plus it absorbs volatile compounds so it's better for the home.
Herdwick sheep run around the Lake District mountains all year round; they're about as wild as you can get for a domesticated animal. They produce a coarse, wiry wool that is a range of different shades from brown, dark grey, light grey, to white. All these colours are mixed into this product making it an attractive natural grey colour. You can read about how we source our wool here.
