Not so much, from the conservatory, more from within.
My wife stuck these butterflies, perhaps a dozen or so, on our bi-fold doors. Shortly after our conservatory rebuild was completed. The butterflies comprise two pairs of wings. One set sticks flush to the glass and has a reflective backing which catches the sun and is further reflected on the inside of the double glazing. The other set of wings stand proud, giving some depth to each individual butterfly.
Their purpose was to help prevent our grandchildren from running into the large clear glass panels. The butterflies seemed to have carried out their accident prevention role, perfectly.
However, there has been a war of attrition, as child after child has discovered the butterflies and ripped off their upper wings.
The photo shows the last intact example, flying proudly, just out of reach….. for the time being.
