Did you dye stuff as a kid?
I used to dye T-shirts different colours. I never tried tie-dye, just straight colour changes, usually from white to something else.
I also changed the colour of my monkey boots from black to silver but I think I used spray-on paint for that.
The dye I used for dying was called Dyson. It came in small round tins, which you had to pierce to get the dye out.
Great fun but could be very messy and annoy Mum when she walked in the bathroom!
