When I'm working on a needlefelted sculpture, sometimes I need small, flat, densely-felted pieces. Maybe I need them for feathers, fins, or eyelids.
Today, I need ears for a black cat, so I'll walk you through my process.
Now, QUICK, lotion your hands, because they're probably very clean, but so dry they feel crispy. I like to fondle Sarafina's lanolin bunny at this point.
When I cut out the shape I want the cat's ears to be, I'll leave an extra flap for the attachment point. I'll loosen the felt on the flap with a seam-ripper, then needlefelt the ear firmly to the cat's head.
