I don't own a Little Black Dress, but now I do have a Little Black Bag.
This is the other thing I made at the felting class on Monday. It's made all in one piece using bubblewrap as a "resist" between 2 layers of wool. When it's felted to a certain level, you can cut a piece off and voila! A seamless bag.
Like all things when you're just learning, it's not perfect. Some of the decoration didn't felt on well and I have had to needlefelt it on with my embellisher, breaking several needles as I went due to the thickness of the felt.
Oh well, that's what learning is all about. If you never try anything for fear of making a mistake, how do you ever get to learn?
That's my philosophy for a lot of things in life. Some of the most important things I've learned have come about through making mistakes.
