Thanks again Lynn and thanks Di for the suggestion. I've managed to log on to the bead mag forum now, so will try a posting there too, although it seems from replies on here that:
a. It doesn't matter whether I cut the thread or not and
b. I can finish it off however I like
I'm planning on a nice mix of brown seedies for this, so might give it a whirl either later today or tomorrow.
Thanks again for all your replies,
CQ
