I have just bought 3000 needles and over 1000 g of pins for my installation at Salts Mill for the Cloth and memory exhibition in July. That is a lot of pinning! I worked out how many pins and needles I need for an area 20 cm square and multiplied the results up to work out how many I need to fill the curtains I am planning to hang. The curtains will be over 3 m long – hence the vast numbers of pins and needles. I ordered all the materials yesterday and was delighted that the pins, ordered from Morplan via standard delivery, arrived this morning. I hope the other materials arrive as promptly so I can get started.
