Preparing paper for calligraphy?

I noticed that the calligraphers in Turkey do some tricks for paper they use for their final calligraphy work.  I am not sure what they do to the paper to make it smooth and better.  Does any one know how or what to apply to normal paper to make a great paper for calligaphy?

I found a site that may be a help if you are still interested:
It should be fine as is, is it wrinkled? You could iron it.

Maybe the paper that you can get in Turkey is not as high quality as you can get elsewhere. I don't know what would need to be done since most places you can get paper that is already perfect.

What problems are you haveing with the paper you use?
