pressing

I'm not an expert in any of this, so I may be way wrong.

It sounds like this is in an area that can also be pressed from the back side of the apron. This will keep the front side of the apron even. Still use a damp pressing cloth, though.

Just a different way of pondering the issue...

I think you are on the right track, pressing with leveling the field. If that doesn't give satisfactory results, try it with a pressing ham. You will then be pressing in a radius to the front apron so it will help it curve around. You can also use a rolled up towel and will be good for experimenting.

Cheers,
