Here follows a step by step of what I do. I saw how needle felting and felting has exploded in popularity, but I wan't more detail than wet felting could supply and I am a 2dimensional artist, so I adapted some techniques.
First you will need some..
Pre-felt (flat purchased pieces of felt)
Wool Tops/ Fibres
Needle felting needles and handle
A marker and pencil.
Step 1: Step 1
Lightly draw out your design.
For this piece I used a vintage illustration for my design.
When you are confident in your drawing, use a fine marker to make it easier to see.
Avoid detail and shadows. It'll get difficult to cover otherwise.
Needle felting time
pluck a small tuft of fibre from your wool tops. Lay onto pre-felt
Using the barbed needle, secure the tuft into place using a repetitive poking action.
As you can see in the image below, start with the darker areas/ outlines.
