Dyeing Felt

After the Direct Dyeing post on The Felting and Fiber Studio site the other day, Shana asked if the same method could be used to dye already made felt. I'd heard about people dyeing finished felt, but hadn't tried it myself, so I had a go at dyeing a couple of recently made samples. They were both white merino, one with milk protein fibre, and the other with Egyptian cotton top. They turned out well for a first attempt. This is the sample with cotton top after dyeing:
