My internet buddy Crochet Loisirs did a pattern for a gorgeous multi-color pentagonal cardi. French original is on Ravelry and on her site, also aptly named Crochet Loisirs. It gathered some interest on Rav, so an english translation was needed and I made it with the agreement of the creator; hope it reads OK. I'm trying to convince her to upload it to rav but you can find it at the link above.
