Supplies for eco printing on paper including watercolor cards, alum, scissors, a roasting pan, various leaves, brown paper and more.

Supplies

Safety Note:

You'll want to wear gloves for this project and work in a room that is well-ventilated or possibly outside on a hot plate. Make sure you know what plant material you are using.

Here's a link to a list of plants for reference. Most of these refer to eating the plant material. Still, they may give off toxic fumes that could be a problem.

How to Create Eco Prints on Paper

Collect your plant materials. Above is a list with labels of the leaves I used.

Good Plants for Eco Printing

Those that are rich in tannins are said to work best. Here are some that I used and a few I've read about that work well.

Watercolor card with sheets of brown paper cut slightly larger.

Cut up some brown paper to layer between the sheets of paper to prevent excess bleeding through.

Watercolor cards in a water with alum.

Soak your paper in a mordant. This will allow the paper to accept the natural dyes of the plant material. I used an alum and water solution. You can easily find alum in the spice aisle at the grocery store.

Leaves soaking in iron water.

Next, soak the leaves in an iron mordant. I used a little ferrous sulfate with water that I purchased online in a foil pan. However, you can create your own iron water at home but it takes a week or two to make.

Soaked leaves arranged on prepared paper on a glass trivet.

You also need something to hold the paper and leaves together. I used two glass trivets from the dollar store. However, you could use ceramic tiles or possibly wood scraps.

Place one of the sheets of soaked paper on the trivet and then arrange some of the leaves on top. Cover with another piece of paper that was soaked in the alum water.

Brown paper layered between leaf prints.

Next use 1 or 2 sheets of the brown paper you cut as a buffer for the next set of papers and leaves.

Stack of cards with leaves and brown paper between glass trivets and wrapped with string.

Continue stacking paper, leaves, and brown paper to make a bundle.

Top with another trivet and tie the entire group together as tight as possible with string to ensure good contact.

Next, you want to simmer the entire stack in enough water to cover on the stove. I used an old roasting pan. You could also use a large pot. However, this is something that you don't ever want to use for food or cooking in the future. A good place to find an inexpensive option would be to go to a thrift store and buy a cheap old pan or pot.

Lay your bundle on some newspaper or old towels to cool for a few minutes before cutting the strings.

Card reveal with one leave still on.

The reveal is the most rewarding part. Above you can see some of the plant material still on the paper. This is actually the top piece of paper.

Cards just after heating.

Here are all four of the arrangements I used. Each arrangement made two unique paper prints.

Leaf printed cards hanging on string with clothespins to dry.

I hung them on some string to dry well but you could also lay them on some towels or newspaper.

Opposite paper eco prints with leaves.

Here are two of the cards that had the leaves sandwiched between them. Both are beautiful. The one on the left is the one where I placed the leaves faced down.

Ironing dry curled paper to flaten.

Once the papers dry they may curl a little. You can flatten them between some heavy books or use a warm iron with a piece of brown paper on top.

Four eco printed cards.

I love the way these turned out. I might try it again in the fall to see what happens with fall colored leaves.

Materials

Instructions

  • Soak your paper in a plastic bin with water and 10 % alum mixed in. I used about 2 cups of water and 3 tablespoons of alum for about 15 minutes.
  • Soak your leaves in water and 1% ferrous sulfate or homemade iron water for 15 minutes.
  • Set the first alum soaked paper on the glass trivet or ceramic tile.
  • Arrange leaves on the paper.
  • Cover with a second piece of treated watercolor paper.
  • Next, add a sheet or two of brown paper as a buffer.
  • Repeat with a new card and leaf arrangement.
  • Continue with more paper and leaf arrangements.
  • Finish with another glass trivet or ceramic tile and tie the bundle tightly together with twine or string.
  • Set in an old non-food use roaster pan or pot covered with water.
  • Bring to a boil and then reduce the heat and simmer for 1.5 hours.
  • Remove from the water and let cool.
  • Cut the string and open the bundle to reveal your prints.
  • Set on towels or hang the paper to dry.
  • Upon drying the paper may curl. Flatten by covering the curled paper with brown paper and lightly ironing or set some heavy books on top.

Notes

Make sure the pots and pans you use to soak or heat the materials will not be used for food in the future. You can easily pick up some inexpensive pots/pans in a thrift store.
Know your plants. Don't use anything toxic or poisonous for this project.
Wear gloves and work in a well ventilated area or outside. You could also wear a mask.

    The results look really interesting. I haven't seen this technique before. I've done leaf printing before just by bashing them with a hammer!

      It's definitely a fun project to try Jenny. A little more work than flower pounding but that's so fun too.
