First, cover all of the place you want with your main texture, using weight hardness, etc. 1.00.
Then, choose a secondary texture, (depends on what you want, but earth, steppe and turf are usually good choices. If your terrain is snowy, snow will always be your secondary texture.) lower the hardness and the weight to something like .20. Imagine that 1.00 is the paintbrush in Paint, and lowering the numbers will turn it into a spray paint.
Then, start spraying the village texture on the desired spots for a path. Weight and hardness should be about 0.30 here. Once you're done, you can diversify by adding other textures in the mix, if you wish. Use something like .10 for these, you don't want to overdo it. If this completely erases the original texture, add a little back in with .10 once again.

If you wish, you can also use ground color paint for various colors on the ground, which is useful for blood, etc., but remember to keep the weight and hardness down for this.

This is *one* of the things that separate a beginner from a learned scener, so it's important that you can use it. Basically, once you get the gist of it, you'll rarely be using 1.00 values except for the initial pass over the area.
