Some internet searching for 'vintage Christmas cards' found me a delightful assortment of old vintage Christmas images. I settled upon a snow scene depicting a small village and a handful of residents, dressed in their best surrounding a tree.
I printed the pictures off and laminated them to stabilize, then punched little holes in the now 'presentation cards' using a pin to allow for the earrings to attach.
I really am quite pleased with how these turned out. Like I said, a simple search on Etsy for 'resin flowers' will unearth more choice of colours, sizes and styles than you ever thought possible (well, almost!). Cheap to make compared to the price you would pay for these at most market stalls.
Simply change the image of the presentation card for this to be an any-time-of-year gift!
