ok i now i'm new to this.i see that a lot of you guys are using grids . question is where do i get some grids or do i just use a spreadsheet to print up a grid- if so what are the sizes to use. if anyone got one already in design ,can you post it up.i have collected a lot of nuggets from around the world,a lot of time i pay to much for to little - but hey i check the gold spot and it's slow coming back my way.
