If you don't know how to make faces, DONT MAKE THEM.
You probably used microsoft paint to make the faces but you can resize the faces with it and you don't need any program to packaging the faces.
Search a tutorial for packaging the the right way.
There is no blockland decal editors. I recommend paint.net its easy to learn if you actually try it.
There is a reason to hate your posts if you don't test your addons package them properly or even use any time for making them.
Please use time when making any content to any community and remember they might like it or not but you should never take too much to yourself from it.
Please think before saying anything when you get constructive criticism and don't do it like this.
