Step by Step Eco Printing on Paper

Summer is in full swing in my garden, so that means I’m eco printing on paper all the leaves and flowers I can lay my hands on. I’m stock piling printed papers and fabric to make books during the barren winter months. Over the weekend I posted a video on Instagram showing me unwrapping my steamed bundle and I got a lot of questions, so I wrote this post to show you how I did it.

Please note that I’m not an expert on eco-printing and there are many wonderful books out there by folks who really know what they’re doing, such as India Flint’s Eco Colour. I’ll just show you what works for me.

Step 1: Mordant the Paper

I dissolved 1 teaspoon of aluminum sulfate in a cup of hot water, then added it to 2 gallons of cool water. I tore 2 full sheets of Rives BFK paper (175gsm weight) into smaller pieces and soaked them in the solution for 2 hours (but often I do it overnight).

Step 2: Prepare Bundle

I gathered leaves and flowers from my garden. Some botanicals work and some don’t work – just experiment with what’s available where you live. I used maple, dogwood and red oak leaves; leaves from shrubs, such as smoke bush, hydrangea and sand cherry. I had good luck with thread leaf coreopsis and some interesting but blurry prints from delphinium flowers (below)

I layered the botanicals with the pre-treated, still wet paper, added a piece of corrugated card board on the top and bottom of the bundle and used binder clips to hold it all together.

Step 3: Steaming

I have an electric turkey roasting pan set up on my back porch so that I can make these prints whenever the mood takes me. I place a brick in the bottom, so the bundle doesn’t touch the metal because it will burn. I add a couple inches of water and heat until the water is simmering. Then I place the clipped bundles on the bricks and weigh them down with more bricks. I steam it with the lid on for 2 hours, checking the water level periodically so that it doesn’t run dry.

Step 4: Reveal the Prints

I remove the bundle using a heat proof glove and allow to cool for an hour. I carefully remove the clips and unpeel the layers. I like to do this while it’s still wet because if you allow the leaves to dry, often they will permanently stick to the paper. Here’s a video of the unveiling:

    Wow, Ali! This looks wonderful. I’ve been wanting to try this for awhile and this is the perfect inspiration. My garden is in full bloom so there’s lots to work with. Can you tell me what Rives BFK paper is? What type of papers work best (weight wise]. Thanks for the video reveal. Beautiful.

      Hi Sharon – Rives BFK is a printmaking paper. I used a white version with a weight of 175gsm. It’s available at all the big online art supply stores. Be sure to share what prints you can get from your garden!

  2. Yes, BFK paper is new to me too. It looks like it comes in different weights – 280 gsm down to 115 gsm? What weight would you suggest? Also, did you use white, cream or cream-white (colors available at Blick’s). Approximate size that you tore a sheet into? Are the sheets wet when you do the layering or do you need to dry them before adding the flowers? Love the look! Thanks for this great video!

      Hi Pat – great questions. I used the white BFK in the 175gsm weight. I tore into strips that measured approximately 4″ x 11″ and the paper needs to be wet when you add the botanicals. Hope that helps.

  3. Thanks so much for posting! Aluminum sulfite can be bought in a hardware store? An art store? Secondly, I have those big lobster pots and a portable electric burner. Coudn’t I use the lobster pot and the burner? Eager to try this and hope what I have will work!

  4. Yes, I was wondering if I could steam on oven too.

  5. Thanks so much for the info and the inspiration. I will give it a try! Your generous heart and sharing spirit make this world a warmer and better place.

  7. This is very interesting. You have a lot of dedication to this process and it has wonderful results!

    I like your video, the steps are very clear. I’ve tried this before, once by submerging and simmering in water with alum and another time by painting the solution on the paper first and then steaming in a kettle over a hotplate. I like the second method better, less mess and the paper doesn’t tear when you peel the layers apart.I do not understand what gsm stands for. I am accustomed to using paper with pound rating, such as 140 lb. watercolor paper. Can you enlighten me? Thanks, Ali. I always enjoy your posts.

  9. This looks like a heap of fun. Thank you for sharing. Will have to have a think what I could use to steam some paper in.

    Ali, thank you for the helpful video. Your prints are lovely! How many papers do you put in one bundle? Thanks!

    Wonderful tutorial. Can this process be done safely in my kitchen with a roaster pan dedicated to art stuff only?

    Does your bundle of papers and vegetation actually sit IN the water or above it?
