The dyeing methods I will be using are the ones I found, while searching the net; dye and mordant and natural dyes. For the brown colour I'll be using juniper both for mordant and for colouration and for the tan one I'll use salt as mordant and black tea as dye.
I have many junipers standing in my garden, some still green, others turning brown or allready dead (or so it seeems). I started collecting the needles as basic ingredient for the mordant, mixing green and brown ones and using bits of every tree/shrub. At first I clipped of some of the lower branches and started to rid them of their needles by clipping them off. I very soon found out that didn't work very well and it went a lot easier and faster by stripping the branches with a gloved hand. And you do need those gloves! Good, sturdy leather gloves, because those needles are like.... well... needles!! It wasn't long befor I figured I could do that stripping directly from the trees too. taking care not to strip the branches of all their needles, i started collecting them by taking a bundles of small branches between my hands and then rubbing those, as if washing them. Many needles fell off in the waiting bag. It did take a while to collect them, but it felt good to stand there, in the snow and freezing cold and collecting some of nature's resources directly at the source and be able to use them directly too.
Only too bad I could not harvest any berries. There were but a few very small ones left on the plants.
