1. Open an image editing software of your choice. I suggest paint.net.
2. Create a new image file with that software. Please note: The face MUST be this size: 256x256 pixels.
3. Draw the face. Save it as whatever name.
4. Now, the packaging. Create a new .zip file and name it "Face_Whatever.zip" (No ")
(Replace whatever with the name of the face. REMEMBER: Do NOT use spaces use underscores, which are these: _)
5. Make a new folder inside the zip file. Name it "thumbs" without the ", and no uppercase letters.
6. Now, drag your new image file into the zip and copy it and paste it into the "thumbs" folder.
7. Now, create a new .txt file with notepad. Inside, write this, and replace the text where it says to do so.
Title: Title goes here
Author: Your Blockland name here
(Some description here, without the ().)
8. Close it, drag it into your add-ons folder, and you are done! Congrats, you made a face!
