The picture above is of a wool kilt that I made and it does not need ironing often but I had just moved a Velcro closure strip because my waist has gone down two inches since I made it. I'll tell about this kilt in another post.
I hadn't intended to do this job at this time but SWMBO (she who must be obeyed) had a pair of pants that needed hemming so I had the irons out anyway. When I set up the sewing machine I automatically set up the ironing board. Having it handy makes sewing so much easier.
The reason for two irons is so I have a cold iron for drawing heat out of a pleat I have just steamed. That helps to set it. The white steam iron on the right is very light and does a good job of steaming. The iron on the kilt is twenty years old or more as it still has a cloth wrapped cord. I works fine but I bought it for it's weight (thrift store one dollar). It weighs more than double the new iron. For years I have looked for a cast iron type that is set on the stove to heat but every time I find one it is an antique and to costly for me. Mostly those end up as doorstops or bookends I think.
The technique I use is to set it on a pleat just ironed while ironing the next. This iron will cover two pleats. It may sound tedious but the results are worth it.
