Wash the top at least once to remove any residues in a new garment.
Cover your entire worktop in plastic sheeting, and wear rubber gloves.
Wet the top and take a large cylinder, like a straight-sided paper bin to slip inside the top.
Arrange the top around the cylinder. Take non-staining string and fasten it around the whole cylinder and top at one side. Continue wrapping the string 6-7 times. Holding the string tight, squeeze the fabric where you string-wrapped it so that the fabric puckers up in little rolls. Pull the string tight. Wrap the top for another 6-7 rounds and squeeze the fabric against the pleats you already made. Continue in the same way until you have wrapped string around the entire top.
Mix equal parts dye and water. Paint dye on the top using a wide paintbrush until all the fabric is soaked in dye. Leave the top to take up the dye for 24 hours.
Cut away the string. Take care not to cut the fabric.
Fix the dye by ironing the fabric without steam for 5 minutes.*
Give your top a whole new look using fabric dye! For this project, we used a special Japanese Shibori resist-dyeing technique, which involves placing the fabric around a cylinder and then wrapping string around it. Instead of tie-dye where you tie string or rubber bands around the fabric, here you wrap string around a cylinder and then pull the fabric out between the gaps. The result is stripey, a bit like the stripes on a tiger. The runny watercolour fabric dye works on fabrics with at least 50% cotton content (as well as silks).
*Alternatively, fix the paint in the oven at 150 °C for 5 minutes, but make sure the garment has no buttons, elastic, or heat-sensitive features. When fixing dye in the oven, it is important to make sure that the fabric does not touch the oven heating element.
