Cosplay help?

Okay I have noticed many coslayers post patterns online for costumes or outfits but I have found that there is usually NO WAY for you to make the pattern bigger with a normal printer so I was wondering if you guys had any advice or what you do to make the pattern largwe to you use.

You could always use paint and click on the re-size button. But if you are trying to re-size it on a A4 into landscape or portrait.

It would be this:

2480 X 3508 pixels - Portrait
3508 X 2480 pixels - Landscape

Just don't forget the copy the pattern first and paste it in paint. Then you re-size it.

I hope it helps. :>

Thank you
