Even though the difference between pressing and ironing has been mentioned, it rates repeating.

Do not iron kilts!!!

Ironing would be placing the iron directly on the fabric and moving it around. DO NOT DO THIS!!!

Alway press kilts.

Pressing utilizes a pressing cloth. Damp to wet, depending on your fabric. Carefully arrange the kilt, aligning everything as you want it, then apply the pressing cloth. Once the pressing cloth is on the fabric, you can apply the iron and then you can move it around, but gently. You do not want to stress the fabric. Press the kilt, don't iron it!!! Keep the pressing cloth damp, adjust the temperature. Steam irons are OK, but you will normally get enough steam from the wet pressing cloth. Some people recommend basting the kilt first, sometimes you can get away without it. You be the judge, it's your kilt. If in doubt, baste the kilt. It's better to take a little extra time, than ruin a kilt.

Another trick that works for me is to press the kilt when it too is still damp. Also don't forget the inside. This may seem silly, to press the inside, but the kilt will look better when you do the inside too.
