So applied my checker pattern like the tut said and I see my pattern is not lining up correctly. big surprise!

I moved my uvs around a bit in the layout editor but I can't ever seem to make them look perfect. some of my checker patterns are really screwed up like running diagonally or the pattern is way stretched to make the small boxes really long boxes.

I'm not uving complicated objects, just some box-ish shapes to get the hang of it.

I'm confident once I get past the stretching issue I'll be doing a lot better but I don't understand why this keeps happening??
