Ok, here are some pictures. I just spot checked my seam allowances, 1/4", there were a few just literally a hair width over. I had spot checked several pieces while I was cutting with my new gadget and they were all correct.
I'm going to have to put this aside, and start again with some old fabric and see how it works, being much more aware of my allowances and widths. I've just never had a problem before, with seams matching, so it's kind of blown me away! I was tickled pink, cutting strips like crazy with the new thingy I got, sewing them all togther.... then ooops. I love this pattern, have seen all the different ways you all have done it, so I'm going to master it yet!
This tool material I got off equilter.com for my grandson, as his folks just totally remodeled a house, and he was heavily into 'tools' after it. :D
