This looks like it would have once belonged to one of those Goth fashion kids; this accessory I imagine came from Clare's the cheap fashion jewelry for kids.
This belongs to a large plastic plant decoration outside a pizza restaurant. I took it as the plant was large anyway although some daft people would walk in the restaurant and explain to the owner it had come off their plant.
A tortoiseshell type butterfly but you can see how warn it looks. On reflection the owner probably loved this and would be missing it. I should place it on the wall I found it.
This was found in outside a supper market. Quite clearly its come off a plant recently purchased in store. Would the owners miss it? Perhaps they’ll realise the plant doesn’t look right and return it.
