When I took the pins out I found they had made the edging uneven as you can see above. So I damped just the very edge all round, pulled it into shape and ironed it.
And here is the finished piece. I am very pleased with it and enjoyed doing it.
Now I have an interesting filet lace pattern that has a stepped edge which I would like to make. Puncetto normally has straight edges so I am trying to work out a way of achieving the stepped edge.
