The shirt should be washed at least once and dry before you begin. If the garment is damp, the paint will spread out more.
Protect your table with plastic and wear gloves when dripping on the paint.
Place the T-shirt on the plastic and spread out the fabric as much as possible.
First, fold the shirt in half vertically. Then fold back the top middle section, still vertically. Turn the shirt and fold the middle section from the other side the same way. Now the shirt is a narrow strip. Fold in the sleeves so that they do not stick out. Fold the narrow strip together like an accordion, starting at the bottom and folding all the way up. Wrap two rubber bands around the fabric bundle, one from either direction, like a parcel.
Drip the paint along the edges of the fabric bundle with a plastic pipette, or dip the edges in paint. If you like, you can blend two colours together to create new shades. You can also have one colour on two sides and another colour on the other two sides.
Leave the garment in the plastic for 12 to 24 hours. Unfold the fabric and let it dry flat.
When the shirt is dry, fix the paint with an iron set to cotton without steam for 5 minutes.*
Then it can be machine-washed at 40°C max, and should be washed inside out. Wash the shirt separately the first few times after painting or dyeing.
Make a cool tie-dye T-shirt! Perfect for reinvigorating an old shirt that you’ve grown tired of. Tie-dye can be done all sorts of different ways! To make this cool checked pattern, first you fold the shirt lengthwise, and then width-wise like an accordion. Keep in mind that the paint will spread out more if the garment is damp, so to create a clear checked pattern, we recommend dyeing a shirt that is completely dry. The thin fabric paint can be used with clothes that are made of at least 50% cotton (or silk).
*Alternatively, fix the dye in the oven (not silk) at 150°C for 5 minutes, but make sure the garment has no buttons, elastic, or heat-sensitive features. When fixing paint in the oven, it is important to make sure that the fabric does not touch the oven heating element.
