Using 2 grout colors on one piece....
Here is the tree I am currently making. I'd like to grout the trunk, branches and roots with a mocha (but willing to hear other suggestions) and the rest of the mosaic in another color (yet to be determined). It was suggested to me to grout the trunk, branches and roots now, before laying the rest of the tesserea. But I've seen posts where they say to just mask off the other areas after all the tess is layed, but then I read that doing that, the grouts don't have a defined line between the two, etc. So what IS the best way to grout seperate areas with different grout colors?
I don't know how to add a photo but here is my flickr site
