I cannot send PM since I am only level 0. about the question you ask, I try my best to answer it by word.
when you stitch a Biscornu, there is two part, up and down. you need to sew them together. when you sew them together, every 7(this is the number I used for big one, and 2 for small one), you add 1 bead before you sew it!
Is this clearly enough for you? if you still have problem, please leave message under that topic so I can answer you there!
