I love this image from the new Lonny of this push pin baord made from a vary large ornate antique frame and an interesting fabric. This one is fabulous because it is SO large a framed painting is even hung ON it. Scale is so important in creating drama like this!
I’d suggest keeping your eyes peeled at flea markets and on eBay for oversize old frames like this (which I have seen at Brimfield in spades). However if you aren’t keen on hunting one down, these bulletin boards have it all done for you- just find a great fabric or even wallpaper and spray mount it to the cork or use small silver tacks to attach around the edge (like nailheads).
They aren’t cork boards, but I found this awesome Etsy vendor who makes these fun chalboards from vintage ornate frames too…. great for a kitchen, office or kids room.
