One year ago, same time of the year I made some oak seeds grow, you can read the story here. And now, one year later I picked one of the little trees, washed the soil from the roods and dried the plant between some paper sheets.
After 2 weeks, the plant is dry enough to frame it. I cutted some fabric sheets to the same size like the glass frame and I clamp the tree with some paper clips between a thick layer of textile and glass…. et voilà my self made oak herbarium.
