ACRYLIC WATERCOLOUR on T’SHIRT

Derivan Fabric Fixative is a great medium for the all-round artist who would like to try fabric painting without buying a large range of fabric paints. It allows you to use your existing acrylic colours to paint a lasting artwork on fabric. Here is a simple watercolour design that you can try at home.

STEP 3

You will need to place the cardboard inside the shirt - this is to prevent the fabric ink staining the backside of the shirt. Now attach the embroidery hoop to the front of the shirt. Be sure to make sure the fabric is stretched firmly with the hoop.

STEP 4

To get the watercolour effect, you will need to saturate your painting area with your premixed fabric fixative mix. Apply generously to the area within the embroidery circle.

*Hot Tip: Fabric fixative drys very quickly, so you will need to work quickly

STEP 5

Start with your premixed magenta paint in your design. There are no rules here; in this example, there is a thick and thin application. *Hot tip Leave areas of white to create exciting patterns

STEP 6

Repeat the step above with the Phthalo Green green, continuing to lay the colour down thick and thin. Notice where you put thin layers you are creating a mix of eyecatching purples.

STEP 7

Remove the hoop once the design is touch dry.

Leave the design to dry completely overnight.

You will need to heat set the design to keep your colours bright and vibrant.

*See below heat set instructions.

Heat fixing prints

It is necessary to heat fix the image if it is to be washproof. Heat fixing can take many forms. The main points to be observed are:

  • The image must be air dried before it is heat fixed.

  • Ensure the heat is applied evenly over the image.

  • Ensure the heat is applied continuously for the required time over the image.

  • Be sure not to scorch or burn the image or garment.

  • Any type of heat can be used. Heat tunnels, ovens, even the humble household iron can all be used. If using contact heat (for instance an iron), use a tea towel or another piece of cotton cloth over the image to iron on. Do not iron directly over the print.

Heat fixing times and temperatures vary. However, a guide is as follows:

Cotton, calico, linen, rayon - 4-5 mins at 140-180°C

Synthetics, nylon, polyester, tetron, acrylic - 5-8 mins at 115-130°C. .
