Thanks guys !
If anybody is interested, I got the frame from Ikea for £35 OLUNDA Picture - IKEA
I had to remove the original pictures which was a bit of a pain as they were stuck to the back board, but I am very pleased with the end result.
Looks fantastic, great work there, Ikea do some great frames for projects like this, and reasonably priced too!
There's nothing better than pulling all the items you have for a movie and putting them behind glass, it makes them really pop - Plus i bet you can actually see them now, as apposed to having them on a shelf!
Can't help but wonder, if the backong board would benefit from being a darker colour, you can buy big A1 mount board sheets from ebay or hobbycraft shops - Relatively cheap as well. I think being a darker background would really make the items stand out.
