I had seen your site before and liked it very much. I don't think I signed your guestbook though. The calculator you have put on your site is wonderful. I haven't tried knotting before, but you made it sound not too bad.
Keep up the good work.
I put in a pic of a pearl bracelet I did with no knots. BTW, I sold that bracelet and now have an order for matching earrings.
