I iron only pure Irish linen. I find this a useful limiting policy. I do not have a similar limiting policy on the possession of pure Irish linen, however, and my mother constantly discovers new stacks of best-quality ancient handkerchiefs to bestow on me, so it is necessary to keep up with the ironing.
To iron pure Irish linen, or I suppose lesser textiles, ironing water is useful. You squirt it at the item to be ironed. Do not put it into the iron itself. It will dampen the creases, and if you put lavender in the water, then your handkerchiefs will smell faintly but elegantly of lavender.
It is not so easy to find ironing water in the shops, though. It was formerly available, presumably when ironing was fashionable, but now it has more or less disappeared. So I consulted the internet and found this. For the first stage I think it is best to use a glass bottle, or a jam jar. Wash this, and into it put 100 ml vodka and 12 drops of pure lavender essential oil. Cap it, shake it up, and let it stand for at least 24 hours. Then add 350 ml water (boiled or filtered if need be) and transfer it to a spray bottle. I have tried it, and nothing bad happened to the ironing. The original instructions say to keep it in the fridge, but I can’t for the life of me think why.
