Large Rocks for more creative space

It is difficult at times to find the best rock for a particular project. Many large rocks have slight flaws or holes in them that taxes rather than enhances my creative ability.Below are some samples of recent projects that have worked out well, because the rocks have been in good shape in the beginning. Mexican Pebbles are my favorite stones, but they only seem to be hand size before they become a little too misshapen for my purposes.This isn't to say that there may be some perfectly symmetrical ones out there. I am more inclined to stick with Sandstone or Tufa stone to accomplish the desired result
