I used a company called Polargram who offer a minimum of 12 photos in either traditional polaroid style, or a newer full square design for a measly £6 - and this includes postage! All you do is select your instagram photos - I did mine via my phone and order away. It takes a few days for them to arrive, all boxed up with a sweet to chew whilst perusing your choices!
I'm definitely going to use the service again. This photos are to go in Agatha van (one she is ready to move into that is) but it's brilliant to have a permanent memory of something that is only actually on my phone, like the photo my 5 year old drew of me a few years ago.
And the one of me, Daisy, and Mrs B together at Hope & Elvis.
By the way, I've just seen the cover for the next edition of Pretty Nostalgic Magazine (due out first week of September) and I think it's gorgeous. The other fabulous bit is that I have a second article in there - I've written the 'taking tea with' section on my idol Agatha Christie - squeal. If you can, do grab a copy, it's worth every penny for a magazine that is page-to-page articles that you want to keep forever.
Happy snapping (and reading)
