Pixelling is something anyone can do, even small children, and what you need is just a simple program - MS Paint.
This tutorial was created by me 6 years ago and teaches you how to make a simple cute blob pixel in 15 minutes flat. As you get used to the idea of pixelling, you can even move on to creating gifs out of the pixel images (I may make a tutorial soon on how to make a gif)
Step 1: Opening Up MS Paint
Click on accessories and then on Paint.
When you have opened up Paint,click on "attributes".
Step 2: Preparing to Pixel
Make sure the units is "pixels"
and the colour is "colour"
Click on the magnifying glass and press 8x
Step 3: Finished Work
Press ctrl G on your keyboard to see the grid.
Start drawing your own picture or if you want, you can follow the example above.
Step 4: Finishing Your Work
This is a good activity to do on rainy days when you have to stay at home or when you have a creative spark going on.
