Today I braved the shops and after much deliberation purchased a mandolin slicer. Naturally I read the instruction book carefully, particularly noting "The blade is very sharp. Take Care". And proceeded to slice up the zucchini my neighbour had kindly given me. But...
A hunk out of my right thumb and copious amounts of blood later I have a bandaged right hand and the thumb is throbbing and there will be no hardanger, nor any other form of handwork done here for a while.
But Cynthia had asked the name of the Hardanger book from which I learned the knotted picots so here 'tis.
Early Style Hardanger - by Yvette Stanton It is available from her website here but for reference the ISBN is 978-0-9757677-1
I have a couple of completed items so may be back in a day or two with some photos.
