First, wash the shirt to get rid of any residues. The fabric paint works best on light fabrics.
Protect your table with plastic and wear gloves.
Pour the paints into various paper cups. Dilute the paint with a little water to create slightly more pastel colours.
Decide whether to paint the shirt wet or dry. The dye spreads more if the fabric is wet, so it all depends on the effect you’re going for. You can also lightly spray your garment with water as you work, so that the dye only spreads a little at a time. We started with a dry shirt in order to keep some areas white.
Scrunch up the shirt. Spatter the T-shirt with paint using a pipette.
Choose a new colour and scrunch up the fabric again, if needed.
Unfold the shirt 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.
Reinvigorate old, washed-out cloths with fabric paint! For example, you can turn a T-shirt into a summer dress that is perfectly sized for child. We used thin, watercolour-like fabric paint to create a fabulous, flowing pattern on our dress, but you could also use this paint for tie-dye projects. Bear in mind that the paint spreads more when the fabric is wet, so if you want to keep some areas free from colour, the fabric should be dry when you begin. The fabric paint can be used with clothes that are made of at least 50% cotton (or silk).
