Err - you just have a go

Actually there is a felters Guild so help is at hand. There are several ways to felt. You sometimes see 'boiled wool' jackets etc for sale - that is felted wool. One way to felt is to knit something, such as a bag, much bigger than you want the finished article, then put it in the washing machine, with something to separate the two layers, and something lumpy such as a pair of jeans to do the bashing. It will come out smaller and felted, ie with the individual wool fibres bonded to each other.
Felting can also be done with a long needle stabbed repeatedly into the carded wool - people make little dolls, birds etc like that.
The most common way to felt is using hot water and soap. First you card a lot of fleece and lay the batts out so they overlap and the fibres lie in various directions - not all facing the same way. Sprinkle very hot water over the pile and gently work it into the fibres. They will start to stick to each other and you keep working, adding more hot water and soap, until the fabric looks like a fluffy blanket rather than the original pile of wool and has shrunk quite a bit. Then you place it on some bubble wrap and roll it tightly. The roll needs to be rolled back and forwards for a while, then the developing felt taken out and 'shocked' by throwing it hard onto a surface. Eventually after a lot of handling, you will have a piece of felt. Nuno felting is much finer and uses a base of a piece of silk cloth, with tiny amounts of fibre added, with whisps of coloured silk fibres added to create a pattern. You can make beautiful scarves that way.
If you look on Utube there are videos of felting so you can see what I mean. It's very much of a messy, hands-on job, but something children absolutely love to do. The ultimate felt is a yurt cover. People who live nomadic lives in places such as Mongolia, make their yurt/tent coverings of felt using the wool of their own sheep. When it comes to the rolling bit, they put a long pole up the middle then drag it behind a horse up and down for ages. There is a Utube video of that too., probably under 'mongolian felting'
