Simple antique/old paper from used tea.
Step 1: "Painting"
This is very simple. When you have finished steeping your tea, removed the bag and use it to "paint" the paper. I used very cheap "bond"/printer paper. The key is to cover the entire sheet. Lay the paper flat and allow to dry. I am using green tea (Sencha) here.
Loose tea can be used also but it is a bit more messy. After steeping. I poured the wet leaves on the page and spread them around. I found if I leave the tea leaves to dry on the page it creates nice, random spots.
Green and black tea can be combined. I found it interesting to use black tea to create spots and then "paint" with the Green tea. Creates a nice "aged" look.
Using various teas, time of exposure and repeating the process, it is easy to create a wide spectrum of colors. Please don't waste precious tea- enjoy it and after drinking get one more use from the leaves before disposing.
