Well after many abortive attempts to do this I've finally got the first 'good one' finished.
Part of the problem was doing the front as BC3 decided to go walkabout and left me in the lurch. I'm working on the pattern - text is always done as I go along. The drawings need to be finalised and then it'll be 'good to go' on the pattern site.
Top picture is the front and (obviously) the bottom is the back!!!!
The working title for the design is 'Working with Cabochons' but if anybody can think of a better title I'd be very grateful. This design needs NO glue if worked with the correct thread - size 20.
