You have inspired me.... I have started a freeform crochet art piece with wood (If I am ready on Monday I will decide if it is utter sh** or art :-D)
With the cardigan worked out of a centrepiece, I remember a free ravelry pattern I always wanted to try, but never did...

and there are some beautiful patterns which mix crochet and knitting, e.g. by Marie Wallin (you perhaps know them already - because of the Rowan magazines)

And at last I remembered this sweater which is a kind of Irish crochet / freeform crochet mix and it is so stunning:

ok now I stop… Sorry I got overboard with the pattern suggestions... I so love knitting/crochet patterns. Please feel free to ignore everything.
