I'm preserving the beetroots in vinegar, water, sugar and spices with my Fowlers Varcola unit. Lilly likes to help. My hands resemble Lady Macbeth's! I should have worn gloves. I've found a site which will be great for helping me dye fabric with beetroot at Pioneerthinking.com
We also have a walnut tree in the garden :D I see some more dyeing happening. I may even let the kids play with me.
