These mordanted (pre-treated) cotton fat quarters are great sizes for small projects or experimenting! Each piece measures approximately 18” x 21” (may be a tad smaller or larger in either direction), and has already been mordanted, which eliminates a time consuming and expensive step out of your artistic process. Mordanting is considered necessary by many in the natural dye community (myself included), to help absorb and retain natural pigments. Mordanted fabric helps to ensure that the natural pigment, no matter what process used to coax it out, will be more lightfast and washfast, essentially lasting longer over time, exposure to sunlight, and washing.

This cotton was mordanted with aluminum acetate and ferrous sulfate (iron), and can be used for eco printing (also known as bundle dyeing), natural dyeing, flower pounding, etc. Keep in mind that since it includes iron, it will darken or “sadden” natural colors - ie: say you’re trying to achieve a light pink from avocado pits when natural dyeing; you may end up with a darker pink or gray because iron is involved. This can either be beneficial or hindering of what you are hoping for color-wise! Each individual fat quarter will vary in it’s frayed edges as well as color. Discoloration and a vinegar scent is normal. If you are sensitive to iron, I recommend wearing gloves while working with this fabric. Please contact me with any questions or concerns.
