How to decorate a T-shirt like a mosaic: very easily with textile paint in a bottle.
Supplies
a light-colored T-shirt, washed to remove the primer, ironed
bottles of relief paint in pearlescent colors: blue, yellow, green, pink
a textile felt-tip
Pattern drawing
Draw a shape or use a simple coloring (cut it out and place it on the T-shirt using needles or temporary taxtile glue) or draw around a support placed on the T-shirt.
Repaint this outline with the black textile felt-tip pen.
Painting a mosaic
Draw small, random shapes directly with the tip of the bottle, without the shapes touching, alternating colors like a mosaic. It's so easy! Fill the whole pattern.
Allow to dry, then after a period depending on the paint used, use an iron to set the paint: refer to the manufacturer's recommendations, as each paint has its own precise instructions for use.
