tutorial - backgrounds

Here's a background tutorial for ms paint!
I know, it sucks. And there is barely anything there... It's really all I could think up x3 Suggestions would be nice.
I've had this on my computer for weeks, trying to think up other stuff, but no cigar.
Made in ms paint, obviously.

I do hope you find it helpful in someway though!

~Thanks, m00fin.

EDIT: says this is a faster was for the first one:
1. press ctrl+E
2. set width as 100 and heigth as 250
3. fill it an with any color
4. find a darker ( or lighter) shade of the color and draw a diagnol line. make sure there are no leaks.
fill the upper half of the diagnol line with the same shade/color you used to make the line.
5.get the move-around tool.
6. left click and press "stretch/skew"
7. set the horizontal as 1
8. stretch skew again and make the horizontal 500
9. keep stretching and skewing until you have a proper background.

Thank you for the favorites!
