I made it in Paint. I noticed at least one typo afterwards, but it is nearly impossible to edit text in Paint. It's not like anyone is going to see this (except for you and you won't tell, right?).
I'm not sure about scale at all. I think it is important to have a general idea of the layout of your fantasy land as you write, just to avoid confusion and contradiction, and mapping it out helps you remember which direction things are in. When I was younger I would make fairly detailed maps and I found the filling in the blank spots sometimes led to new ideas as I suddenly wanted to include the lake that I added in just because there was a big empty area of the map in the story.
Mapping out your world is an awesome way to plan and preserve your ideas. You don't need artistic ability (as proven by my map), you just need an idea of where everything is. If you need inspiration, you can look at maps made in a similar time period to the one you intend to write in to see what to include.
Oh, dang, I just realized I forgot to add a compass rose. Better tell my friend which way is north.
