You can use sandpaper to smooth it down, just like it was made of wood. The smoother you want it to be, the more effort it will take but it will be worth it. If you try to smooth down the layers as much as possible while you are macheing it will save a lot of time at the end.

If it is rough but strong, you can use a rasp. That will really take off all the bumps. Brush some paste over the roughened surface and polish it with the back of a spoon. Add a layer or two over the top.
Of course the best way is to work really smooth right from the start. Never too many layers at a time; as little paste as possible to get a tack; sanding gently once each layer or layer group is dry.

Hi there, I have found that when layering paper if you use smaller pieces(fingernail size) on the curved parts of the work it will sit flatter. I know it seems slow work, but works out quicker in the long run. Also you must smooth things down as you go, if it won't sit flat, pull the paper off and put a smaller piece on instead. I work on several items at once, doing only one side at a time to make it easier to handle.
