Wow, so pefect! How in the world do you make the horizontal and vertical lines so even and flawless? Do you use a sugar lace design as the grid?

Thank you! @gscout73 ‍ ‍There's a video on my IG page that shows a bit of how I pipe my lines. Sorry, I'm not good at shooting videos, but there's also a post right after it that shows the finished product. Basically, when I pipe my lines, I just pipe vertically, from bottom to top, and I just pipe with a very steady hand. If the cookie is very large, like my 'White Tiger' cookie, then I will use a printed grid as a template. 

Wow, I am so impressed. I would not be able to make them as straight and as uniformly spaced. I see your cookies here and elsewhere and am left in awe. You are amazing.

@gscout73 ‍ I appreciate your kind words, thank you.
