So I've sourced the reasonably priced botanical prints, navigated the online frame design and ordering process, and now have the job of hanging 6 pictures in a perfectly aligned grid. I have a plan involving laying them all out on the floor on a huge sheet of paper which I will mark up and then transfer to the wall etc etc but there must be an easier way. Has anyone nailed (ahem) the technique for hanging pictures? Any tips and hacks?
