I've been working like a busy little bee over the past few days writing this pattern up, and getting photos etc, but here it is :)
It's the Plumes Beret, available for £2.50 from ravelry. Or you can use this link to purchase the pattern
It's a slouchy beret, written for small and medium sizes (20" & 22"). It uses Sirdar Country Style DK, or you can substitute any other DK yarn that gets you 24sts to 4". The lace pattern is both written and charted, and easy to follow.
I think the beret is great for transitional seasons like spring or autumn. It's very slouchy, and quite cute, if I do say so myself!
