How can I fix the tea stain patterns left on flattened tea bag so it can be light/colorfast? Answered
I drip-dry a used tea bag (the folded sachet kind), then open it carefully, detach the stapler, string and label, remove the tea and flatten it wide. On the surface is the pattern left by the tea-stain. What kind of mordant or fixing agent can I use to preserve but not disturbing this pattern on the process? I will appreciate any help and suggestions.
