Materials List for the "Printing with Mordants" online workshop, April 11 & 25, 2021
Links below are listed as examples to help you determine whether you have appropriate materials already on hand or need to purchase supplies. If you have questions, please email workshops@sfcb.org.
Dyes
You will need at least one dye to colour your fabric after printing. I buy a lot of dyes from Botanical Colors and Maiwa in Canada.
You can also make your own bath using red onion skins, various flowers, avocado pits and skins, pomegranate skins etc. If you are planning to do this, please email me ahead of time so I can let you know how to prepare these.
Mordants/Additives
These will be used to make the pastes we print with and prepare the cloth we print on.
|
To clean your materials/fabrics. This is not required unless you are doing a lot and want to ensure that your cloth is thoroughly cleaned. Non scented and natural wash and boil will work just as well. |

Stamp pad
Paste will be poured onto this pad. We will use it for inking up the blocks we print with. You will need two stamp pads total.
|
Stamp pad |
This is housed in a container |
A flat-bottomed rectangular Tupperware container works great |
|
|
a thick sponge (should fit inside the container). If you find something denser, that will work great.. |
|
|
|
2-3 pieces of thin cloth (like an old worn cotton button-down) |
Little larger than sponge |
|
|
piece of burlap |
Little larger than sponge |
|
|
Old credit card |
To even out the paste |
Printing Pad
The fabric will be stretched and pinned onto this. This consists of three materials layered on top of each other. Layer 1 being the thickest at the bottom, and Layer 3 being the thinnest, on top.
You will need only one printing pad.
|
Printing Pad Layer1 |
High density foam (insulation foam) The size of your printing pad determines how large you can comfortably print. I work with 18”x 24” or smaller. |
|
|
Layer 2 |
soft foam (same size as insulation foam) |
https://www.amazon.com/FoamTouch-Dacron10Yx36I-Polyester-Dacron/dp/B01MX... |
|
Layer 3 |
a tight weave heavyweight fabric (larger than insulation foam) |
This fabric is stretched and pinned to the back of the high density foam. |
|
T-pins or any other pins |
To attach your fabric to the printing pads |
For Stamps
A few options for stamps/stencils are listed below.
Pick whichever one you are comfortable with/want to try/have access to.
|
Acetate sheets |
For stencils, if you want to make and use stencils, cut ahead of time or buy pre-prepared stencils (see below) |
|

|
Adhesive backed felt pack |
If you would like to make your own stamps. In addition, you will need corrugated board or high density foam scraps to stick the foam onto |
|
|
Ready-made felt stamps |
I use these a lot to create shapes and patterns on a corrugated/foam base |
|
|
Knife, ruler and cutting mat |
To cut your adhesive felt or acetate |

paint brushes |
Any kind, to brush on mordants |
This is you do not want to use stamps, but want a more painterly effect |
