How to tie-dye fabric:
Moisten the entire fabric bag.
Tie knots on either side of the bag with cotton string. The firmer your knots, the more white will appear in the pattern.
Use a pipette to dot various colours onto the fabric. Squeeze the knots to help the colour absorb thoroughly.
Give the paint an hour to absorb before you cut off the strings. Let the bag dry.
Fix the paint with an iron set to cotton for 5 minutes (without steam) or in the oven at 150°C for 5 minutes. Make sure the bag does not touch the oven heating element.
Wash the bag separately the first few times.
Transform fabric bags into your own personalised shopping bags! These thin fabric paints produce the wonderful look of watercolours and are perfect for tie-dye and techniques in which the colours flow together. Tie-dye involves tying knots around the fabric before dyeing it. You can also choose to paint the bag with a foam rubber brush. Colours that flow together: Start by painting the bottom portion of the bag with the darkest colour. Spray with water and see how the colour runs. Leave some white in between, apply the next colour and spray with water. The paint will move upwards, so wait before adding more. Alternate colours and repeat until you are satisfied. Let the colour seep to the back, or paint the back the same way as the front. Let the fabric dry and then fix the paint.
