Homemade milk fabric paint is a simple paint that you can create at home. It is supple and waterproof when dry, so it is great for painting items that are meant to be worn. Making milk paint takes very little effort and is practically goof proof since there is no "right" way of making it.
Sift the dry ingredients to get rid of any clumps.
Add an equal amount of pigment and dry milk to a bowl. You can experiment with different ratios of milk powder and pigment. For example, more pigment will yield a deeper colour. More milk makes the paint more waterproof and lightens the colour.
Add a little water (1 to 2 tbsp) and stir. Keep doing this until the paint is the right consistency for your project. Thinner fabric, for example, will do better with a thicker paint.
If the paint clumps, use a whisk to mix the paint.
Store the fabric paint in airtight jars in the refrigerator for up to two weeks.
Before using the paint, make sure that your fabric is clean, without fabric softener. Heat-set the paint with an warm iron.
