I found these at Paper and Ink and I think they are all pretty amazing.
I am always amazed at how people can make such beautiful things.
melissa hirsch makes beautiful sea life from... of all things... fishing line. what gorgeous intricacy.
joana vasconcelos wraps cotton crocheted lace around hand made sea creatures (and other creatures) giving them a delicate and elegant barnacle like covering.
helle jorgensen makes amazing sea creatures from pretty much anything. recycled plastic bags, paper, reclaimed wool. incredible.
and jessica polka... beautiful crocheted sea animals, with awesome vintage specimen tags. brilliant.
