It can be pretty hard if they are that complex... Plus I'm not that good in Tutorial-makeing... But if you can maybe tell me what you have problems with, I can try to explain or make it clearer...
I fear I don't really get your question... English isn't my first language, so have mercy with me... Do you mean how to start? Or how to do the spine, like shown in row 10? I can try to draw that...
Oh haha sorry XD i meant the way it's laid out do you stitch it like that first and then you stich the ends together? Or along the way do you stich the ends together?
What ends? I use wire, so I just go through the beads in lines, forming them to a boddy... In the end I seal everything by going back the last few steps...
