How to post crafting ideas

Create crafting recipe on a workbench!
Launch you minecraft, launch a world in creative mode and place a workbench. Then you need to get ingredients for your recipe. When you will get ingredients, open workbench and put them on workbench. If you will get something in icon on the right, then that recipe already exists. If icon on the right will be empty, then we can proceed. After you put ingredients on the grid, you will see something like on 1st image. Now take a screenshot (press F2).

You can close your minecraft now.

Create a ready image!
Now, when you took screenshot, locate your minecraft folder.

Type %appdata% into the starting menu, open folder Roaming, then folder .minecraft

Now open folder screenshots and find screenshot, which you took just now. Copy it somewhere on data D:.

Now open paint, load image from data D:, and cut your image like on 2nd screenshot (click on image to zoom in). P.S: My paint is on another language.

After you cut it, click save and upload on wiki!

Draw, how your item will look like!
If you want everybody to see, how you imagine your item, then draw it in paint!

Draw your item in icon on the right and you will have fully completed crafting recipe!

Oh wait, not "fully completed"! Need to give it a name! You can create any crafting recipe! Your imagination is the limit!
