This groundbreaking workshop will lead students through a number of projects on silk, cotton, linen, wool, and paper. Through contact printing, immersion baths, bundling and binding techniques, and the magic of indigo, this workshop will explore new, uncharted territory on textiles.

In this workshop students will rust print with flat metal and learn bundling techniques to work with sculptural pieces. The class will make two tannin baths to selectively shift colour while working with binding resist. Additional immersion techniques will be taught with ferrous, tannin, and calcium. A special rust-tea bath will be used to give dramatic results on cloth. Finally students will explore the magic of an iron-reduced indigo vat. This is a very creative exploration of the transformative power of materials to create novel marks and patterns.

This workshop is designed to work for you wherever you are in the world. New content becomes available each week over the course of 8 weeks and will remain available for 3 years from the date of purchase. The last module of the workshop will include one live zoom event.

Included in the Workshop:

• 38 evocative instructional videos.

• Concise written instructions and recipes along with downloadable PDFs.

• Access to a robust Q&A section with instructors answering questions 3x a week.

• One live Zoom event to wrap up the workshop and inspire you on your journey.

Learn About ...

Begin with a Quest

Find your own iron pieces for printing and bundling. We give key suggestions of places to look as well as a backup plan to get what you need.

The Flat Rust Print

Learn techniques and formulas to transfer rust prints onto cloth. Begin with rusted or un-rusted metal.

The Bundle Rust Print

The sculptural possibilities to put pattern on cloth are endless. See new potential in shape and form.

Bound Resist

Discover the mark making potential of bound resist techniques. From clamping to binding, to folding.

The Environmental Print

The rust print can also engage the energy of place. Natalie looks at special projects and working with large pieces.

Tannins & Oxides

The relationship between iron and tannin is fundamental to many natural dye techniques. Learn how to get shade variation through fibre type and tannin choice.

Variations on a Theme

The bundled rust print becomes an entirely new process when conducted in a tannin bath, generating dramatic contrasts and complex patterns.

Combinations and Shifts

Explore ferrous as an immersion bath and discover new colour potentials through combinations of tannin and calcium baths.


Indigo brings it all together, providing a complement to the earth palette obtained from tannins and oxides. Patterning takes these works into a new register.

Meet Your Instructor:

Natalie Grambow has extensive experience in the textile arts, and a backgound in design, photography and the visual arts. For over a decade she has also established herself as an exceptional art educator and maker. She is an accredited interior designer, has worked in the architectural design field and has taught design theory.

After completing her arts degree at the University of Ottawa, Natalie studied at the École d’Impression Textile à Montréal and later travelled to Asia and Latin America, where she spent six months learning to weave with local Mayan artisans in Guatemala. Shortly after completing the Textile Arts program at Capilano College, she was awarded the BC Craft Association’s Award of Excellence.

Natalie has developed numerous courses and creative workshops. She possesses an astonishing knowledge of process and technique. She has been a core teacher at the Maiwa School of Textiles since 2004. Natalie is also a working artist. She owns her own sustainable textile design company called La Cochenille based in Roberts Creek, Canada.

Natalie works with natural and gathered materials, employing plant dyes and pigments, foraged botanicals, tannins, metal, rusts, printmaking techniques, felting and stitching. She has exhibited her work in Montreal, Vancouver and the Sunshine Coast, and has been commissioned by such clients as the City of North Vancouver. She is a founding member of the Samara Artists Collective, and has completed solo and group residencies for the Sunshine Coast Arts Council and Fibreworks Gallery. 

This course is the culmination of many of Natalie’s deepest interests. It represents decades of artistic exploration into the ways time changes all materials and can play a collaborative role in the mark making process. The textural depth of her work is an echo of the beauty of materials, coupled with the hand of an artisan and the mind of a maker.
