Be sure to do a test page first. Some printer inks CAN handle being printed first and then going through the 'aging' process, but most don't. I know ours doesn't.
Ball up your paper into a tight ball. I pulled it apart and balled it again. Stick it into a coffee bath. It originally called for instant coffee and water, but I used leftover coffee. We make rocket fuel and knew it would do just fine.
I played with it a bit and started to smooth it out as it began to absorb the liquid. Depending on the thickness of the paper, it can stay in anywhere from about a minute to about two minutes.
Cut and glue to what you’re labeling. I used a glue stick for our project as several labels went on antique bottles and I needed to get them off with ease. Rubber cement and spray glue are great to use if you're not too worried about getting the labels off quickly.
For any 'blood' effects on the labels, just add a drop or red food coloring. Let it soak in for a minute and gently blot off any excess.
