To use the raspberries as a direct stain dye, take out any very mouldy raspberries.
Make a high concentrate lemon juice and water mix. Place the raspberries onto a natural fabric material and spray with lemon juice.
Leave the raspberries onto the fabric until they bleed out onto the fabric material and stain the fabric. You can even press them to make the stains bigger!
Take the raspberries off and let the fabric dry.
