Increase drawString?

I need help with a Minecraft project. I'm currently programming a client for Minecraft, and have just set the custom background. Now I wanted to use 'drawString' to put the client's title down. It works so far, but the string is rendered far too small.

Is there a way to change the size of the string without fonts?

Just implement your own front renderer?

or

GL11.pushMatrix ();
GlStateManager.scale (x, y, z);
// Render text
GL11.popMatrix ();

I have now packed a RenderUtil with my own draw string and it worked
