Permanent textile markers with two different felt tips at each end, which you can use to decorate new and old textiles.

Shake the marker well before use and place plastic or cardboard inside e.g. T-shirts and tote bags so that the colour doesn't seep through and rub off on the back

 When the colour is dry, you can iron baking paper on top and underneath the textile item

After ironing, the colours stay beautiful when washed up to 40°C

Note that the marker is perfect for light cotton textiles etc
