okay, here is a quick tutorial on how I make pixels - others may do it differently, but this is how IIIIIIIIIII do it :D

1. open ms paint
2. go to view, then zoom, the custom, then select 800 x
3. select the pencil
4. let your creativity take over!! have fun....try a bunny, or a kitty :D
5. select a nice colour (dark)
6. colour all the outside pixels with it
7. go to colours, then define custom colours, then choose a lighter shade of the dark colour, then add to custom colours, then ok.
8. colour the inside of the pixel with that colour
9. then repeat the custom colour process, getting a lighter shade
10. colour some of the corner with it
11. colour the corner it self white
12. go to veiw, then zoom, then normal size, and there is your completed pixel!
