I knitted a large flower for a brooch, using Rowan Big Wool Tuft. I really enjoyed it. I then felted it using very hot water, soap, and a good battering in my bathroom.
So much did I enjoy it that I wanted to make another flower. However, this time I'll try smaller, thought I. I ended up using red embroidery cotton as a yarn and darning needles to knit with. It turned out rather well. You can see it in etsy at the link above and also on my flickr page. But I have posted a photo here as well.
In the middle is an antique 19th century glass button. On the back is sewn a silver plated brooch back.
I am really quite happy with it.
