If you don't have Roblox Studio, get it. Open it up.



When Studio is open, you'll be given a Start Page that looks like:

Simply chose "Baseplate" as this will just be a plain surface.


Next, you'll want to create a part.

Once your part is added to the baseplate, you can then Scale the part to make it a little bigger.

Play around with scaling to figure out which way you want to do it.


Once you have your Scaled part, you will need to add a Decal to the Part by right clicking on the Part  and going to Insert Object and then going to Decal.
