Small amounts of different DK wool (Riverdene RG21)

Hello Everyone, I am making this caterpillar, and want to make him 100 sections long, I am up to 73 at the moment but have run out of diffrent wool. Each section only takes 3.5 metres and each one is different . Does anyone have a bag of bits of DK wool in any colours or textures that needs a new home please, I would be most grateful, thank you for reading Anne
