First, sorry for my ugly English, I’m Italian! :P
Pattern is designed by me, if not so clear, let me know! I will happy to help you! ^^
I used crochet hook 1.90 mm, Lamè yarn silver thread and golden thread together (Cross) and white thread (pearls).
After, I’ve sewn some pearls on the cross and then I applied fabric glue behind Cross to obtain a rigid Cross.
Hope you understand me!

Claudia :)
