Take some potatoes, cut hem neatly into half, take a (not so sharp) knife to cut out nice shapes that stay, whereas you cut the surrounding areas lower.
Take liquid fabric paint and a thin brush and put then some paint on the higher ornaments/forms you’ve just cut out.
Make a first try by printing it on a piece of paper.
Make some adjustments to the cut if needed, but if you are happy then go on and press the shaped potatoes onto the fabric you’ve chosen (old ones to repurpose or new; linen and cotton work best); arrange the print in a row, in circles, groups or totally by hazard, close or in a wider distance – even kids can do this.
Let the paint dry (and maybe iron it) and then go on and use this unique piece of art however you want – for gift bags, pillowcases, table runners, curtains, etc… happy sewing!
