Hobbycraft Black or White Deep Box Frame 15 x 15cm 6cm
Hobbycraft Grey Shadow Box Frame 18 x 18cm £6
Hobbycraft White Shadow Box Frame 18 x 18cm £6, also come in black.
If you don't want to put any nails in the wall, there are lots of magnetic hooks out there.
BD Art 9 x 9 inch shadow box frame with 5 x 5 inch opening. Comes in white, black and oak. £10.95
All maps I recommend you use a local framer. I leave a good centimetre of plain canvas showing before starting the frame. No mount, no glass. Frame above is 2cm wide and 4 cm deep.
If you have any other framing suggestions, I'd love to hear, it's really helpful!
