Explore the fascinating process of creating botanical monoprints – dying and printing fabrics with native plants.

  We were all happy with the results

Each two-day workshop will cover:

• how to choose and prepare plants for printing
• processes for mordanting protein and cellulose fabrics with natural metal salts
• techniques using tannins and other additives to enhance your prints
• different procedures of constructing and cooking bundles

Each three-day workshop will cover:

• everything in the two-day workshops plus
• learn how to resist-print with plants and discharge natural dyes with plants
• understand how each mordant brings out different colours from a plant
• in-depth exploration of natural dye techniques working with cochineal, weld, logwood and indigo
• practice of over-dyeing fabrics to create a wide spectrum of colours

Workshops are held in a rustic barn located on 23 acres of meadows and deciduous trees,
minutes from Tweed and 37 km north of Belleville, Ontario.
The setting is very tranquil, with plenty of botanical materials from the property and dyer’s garden.

At the end of the workshop, you will leave with one-of-a-kind, eco-printed silk scarves and
fabrics to use in textile art or sewing projects.

Workshops require a minimum of four students; registration closes at six students,
so there will be plenty of personal attention!

" I have just had the opportunity to share in a most exciting workshop with MARTA MOUKA, Tweed area artist and educator. Marta posted her "Eco Printing" workshop at her Facebook page and a number of area friends were keen to attend. On arrival on the first morning of the two day workshop, we walked into Marta's barn, and found the most amazing set-up imaginable for a group of eager dye work loving students... the main floor of the barn was set up as a classroom - individual tables for each student, an huge array of freshly harvested leaves and plants that would be used to lay out the patterning for our silk and cotton fabric, scarves and more. Each table was equipped with plastic cover, and Marta supplied all of the wrapping poles, buckets, rubber bands and iron pipes Her excellent set-up for the dye pots was impressive - three large base heat stations equipped with individual propane tanks, large and safe pots chosen specifically for the task at hand and she had a nice supply of logwood and alum ready to go into the pots.

After a lovely sharing of her own beautiful eco-printed art pieces that would be our inspiration for the work at hand, Marta carefully led us through the soaking of fabric in iron water, the layout of the natural materials including leaves, plant roots, and named them individually for our reference as we worked. She shared the process of the rolling and tying of the dye bundles before they would go into the dye pots. Supervision and help along the way certainly assisted in our keeping up with the timeline for heading the work into the timed dye process. While we waited, lunch was shared at a restful, shaded picnic table and treats of tea or cool drinks helped pass the time.

Overall, the six students in our two day workshop group were thoroughly satisfied – thrilled in fact with our pieces as they were unwrapped – with many stunning results. I certainly highly recommend this workshop series to those who want to learn from a serious practitioner like Marta, devoted to perfecting her own eco-print work, and as someone who really wants to share her techniques and skills with others. I look forward to the promise of "Part Two" in summer 2016.

What a fabulous and productive weekend. Marta, your organization, variety of materials, up front information and well labeled samples made it wonderful. Then you left us on our own to create but were available to handle questions.
This made it very conducive to our varying abilities.
Thanks for sharing your beautiful barn, property, specimens and mostly yours and David's hospitality.


First I would like to thank you for all you’ve done for us during the time we spent at your beautiful home. The workshop was well  organized and productive and the method I learned works well. Since I came home, I made 3 or 4 small runs and so far everything was successful.
So thanks again.


Thank you for the wonderful workshop. Your preparation for this weekend made activities run smoothly and logically.
The knowledge you shared is very much appreciated. Here are a few pictures of our group.

Just wanted to drop you a quick e-mail to say a big thank you again for the wonderful weekend!  I seriously enjoyed myself and learned lots from you.  Such a good teacher.  I washed all my “pretties” again this morning just to get out any residue dye, and hung them on the line....
it looked so nice, I couldn’t help but take a few pictures of them gently swaying in the breeze....beautiful.

Thanks again Marta.....hope you have a very successful sale in Toronto in a couple of weeks, and perhaps we’ll cross paths again.
