Once I used the level, they were perfectly straight. So there you go. Don’t try to eyeball it.
I decided to do a free-form shape and just let the hexies wander on the wall, if you will. I love how it turned out.
I’ve still got work to do in here: sew the new bedding (the chevron white/grey fabric on the beds in the photos are just the sheets), style the tops of the nightstands, and make something to hold artwork. But it’s starting to come together. Take that plain white walls!
**Update: So, that “permanent” tape is not so permanent. We’ve had falling hexagons, people! Anyone have a suggestion on what will stick without damaging the walls?
