Here is a crochet crown I made to wear in the booth at the CGOA Chain Link conferences and Stitches events this year.
It's made from Filatura Di Crosa's New Smoking yarn in Silver.
This is the crown with some white paper inserted in the middle so you can get a better idea of the stitch pattern.
I'm going to try to take better pictures tomorrow, since these don't really show just how absolutely sparkly and divine it is!
I stiffened it with a boiled cornstarch mixture. It's quite sturdy.
