Beading : St. Petersburgh chain

This my attempt at the St. Petersburgh Chain. I found a good clear tutorial in the http://www.beadingdaily.com/ ..
I have tried this stitch before but not with the success that I have had today. It is has very clear instructions It would be very hard to go wrong with them..
This was actually one of the first stitches I ever tried. That one was from this website http://www.geocities.com/SoHo/Lofts/8782/beads/beadpatt/pattern07_e.htm
The usual thing happened I ran out of beads before I had the item finished.. It was quite a success, but the instructions were not as clear as the Beading Daily one.
I have also tried a bracelet in S.P. that was hard going too but I got there in the end. This was instructions from the bead and button web site. You had to do 6 rows of SP. and it took me a long time to do it.
