I seriously love this idea for the downstairs loo. You could create a screw or catch at the end you can’t see in the picture so it is easy to remove from the wall and put on a toilet roll. They do artificial birds at Rockett St George.
"Mirrors are usually hung singly but they can also be displayed in groups, like paintings. Stick to one theme – here, frameless mirrors – hang the largest one centrally to create a focal point, then flank it with smaller mirrors grouped together in similar shapes." I never would have thought to hang mirrors together!
