Biots are a bit tricky to tie in at first, but with practice it does become a lot easier. I take 2 off the stem and place them in my fingers so the points are facing in opposite directions. From there I measure and use a pinch loop to get them to sit correctly. Another good technique is shown in this video.
. If you haven't already check out some of Davies videos, I strongly suggest you do. I know that they have helped me progress a LOT since I first began tying.
