You can soak the bark in water to soften and then form over a bowl or other item to mold a decorative object. (See the photo of the bowl I made). It will hold its shape once it is dry, but shouldn't be subjected to dampness. You could spray your item with some sort of sealer to protect it.
It can also be peeled into thinner layers for an even lacier look. Fiber can be kept damp for a period of time, but will develop mold if allowed to stay wet for too long.
Google papermaking with mulberry bark to get directions for using this in paper.
You are buying approximately 2 ounces of this fun funky fiber. (Note no two pieces of this are exactly the same - the photo only shows a representation of the fiber not the actual fiber you will receive as this is being sold by weight)
This can be dyed with fiber reactive dyes as it is a plant based fiber.
