Starting to get into crazy felt, so much fun! Most crazy ideas can be realized with this method.
It is quite straight forward - wool and yarn are arranged as you wish on a base material which is water-soluble stabiliser and temporarily attached with a spray adhesive before being stitched in place using sewing machine.
Got this idea in Jeannette Knake book called "Crazy Felt". You can find plenty of great designs and interesting ideas in this book.
And this is my first belt using this method :)
