I have made the lace diamond bookmark which was one of the suggestions from SITN.
The thread I used is a silver grey colour with a silver lurex thread running through it. It is a bit thicker than I would have liked but cjoice was limited. Having said that I think it looks nicer than any of those in the pictures, even though I do say it myself.
I should have let you be the judges but I forgot to take a picture and now it is all wrapped up.
Anyway, thankyou for your suggestions and especially Sally.
