Pirate bag and textile markers offer
The bag is a good size and made from unbleached cotton. The markers are double-tipped so they're great value. Once you've used the pens, you can set the colour with an iron or in the tumble dryer. Once the colour is set, you can wash those items up to 40C. The pens can be used to jazz up old t-shirts, teatowels, pumps etc - be warned - these pens stain clothes!!!
