Thank you so much for showing us that!! It really does make a difference - although not much - I had to stare at it to see the points that weren't matching! I can definitely see on larger blocks were it would show so much more though.
I also wanted to pass on a tip I have learned. It really makes a huge difference using Bottom Line thread in my bobbin. I'm still learning to paper piece so I have had to pull out more seams than I care to admit. the bottom line thread is sooooo much easier to get out, plus, it really stays sitting nicely when you rip out the paper.
Your blocks are fantastic by the way - love the fabric prints!
