How to care for your felt...
Felt is fantastically simple to care for.
Wiping with a wet cloth will remove most stains. If the item needs to be thoroughly cleaned, hand wash it in luke warm water with a plain soap (no perfumes or dyes), then wring it out and leave it to dry.
When felt is worn often, it tends to grow small piles of loose wool fibres. This happens with all wool products. Just pull them off the item, or on smaller thinner items just cut them off. Felt actually becomes stronger with wear.
Steam or Iron the felt to remove wrinkles, you could also do this if it is looking a bit sorry for itself.
