Framing options come in all shapes and sizes, but probably my favourite is the humble Ribba frame from IKEA. These come in a range of sizes suitable for various prints and enlargements, including 12×8″. I’ve never understood why it’s so hard to find frames for this print size, given that it’s a standard 3×2 aspect ratio. However, Ikea’s 40x30cm frame comes with a mount that is ideal for either a 12×8″ or A4 print.
Other frames are suitable for 6×4″ and 7×5″ prints as well as 12×16″ and square enlargements. They come in a variety of finishes, my favourite being the oak effect.
Ribba frames also have a depth of 35mm, which means that photos can be set back from the glazing or mount. If you’re feeling creative, you can also hide lighting effects behind the mounts.
In fact their use goes beyond picture framing – they can be used for imaginative wall decorations, as described in this article at Shelterness.
