Some good Block templates?

So far for making my mod, I have been using the older 1.8.3 version of MCreator to use the Block Templates because I prefer those over the new ones. But the problem I ran into is that it doesn't have a good Sand texture. I know there are some texture template plugins on this forum and I have one installed which has blocks from the Caves and Cliffs update, so I know how to install them. The problem is, I don't know where to find them? Anyone know where I can?
