I wanted the bottles of salt and soda solution for the schools dyeing project to be clearly labelled so I used red (or black for soda) electrical tape. No chance of it smudging into illegibility.
But why, you might ask, was I to be found caressing these bottles with best baby talcum powder yesterday morning? When you take off the paper labels there is a sticky residue left behind. Latex gloves tend to stick to this making all manner of spilling disasters a distinct possibility. Give them the baby's bottom treatment and they're fine.
