I've been trying to think up a nice way to display my brooches for ages when I realised I could just use a frame with some felt in the center to pin them too!
This could look amazing with an ornate antique frame but you can use anything for this. I just bought the cheapest frame from Ikea.
Take the frame apart.
Glue the felt to the front plastic or glass of the frame. Only glue around the edges and don't put any glue in the middle. Leave to dry for a few minutes.
Put the frame back together.
Attach your brooches and you're done!
