So, I was just wondering, what's the best way to remove creases from papers?

Water

methylcellulose or ironing, depending on the paper. for example, tissue papers would use methylcellulose, but elephant hide would use ironing.

Does anyone know how to remove creases from tracing paper?

I know. Use another sheet.

That helped a lot
Can anyone else help me .

removing a crease from tracing paper is almost impossible. it takes a crease just like japanese foil

Removing creases from tissue paper is actually possible.
There is a learning curve involved, requiring keeping note of trial & error attempts while experimenting with different temperature settings of a common electric clothes iron .
Lightly spraying a fine mist of water before ironing does seem to help dissipate the crease memory.
Not too surprising, one needs to practice a bit of finesse and patience to avoid burning or tearing the tissue.
Start with low temperature, gradually increasing, as need be, allowing time in between, until desired threshold is reached.

An update on my ongoing experimentation toward removing creases from paper, especially the prefolded ones from origami-shop.
I am finding that the home iron method is too precarious to the paper, results vary from good to disastrous. Oftentimes the crease will be adequately flattened, but the crease line will still be apparent.
I am moving toward the stack & weight method.
I lightly run a moist cloth over the creases on each side.
On a flat surface, I place a couple sheets of plain white tissue paper, then the target sheet to be flattened, then another white tissue, then a clean 2 foot sheet of poster board.
The sequence is repeated for however many sheets I need to flatten.
Finally, I add weight such as books or bricks evenly distributed over the top surface.
After a day or two, I add a bit more weight.
It is mostly a guesstimate, but trial & error seems to indicate leaving the weights on for about a week, give or take. Obviously, the longer amount of time, the better.
The results seem to be better than ironing so far .
A potential future solution may require ordering the paper , at extra expense, in tubes, unfolded, if possible.
