Wow @curiousseagull £1 for a mount! Mine cost just under £5 so I think I need to do some more research to get costs down! I’ve gone for conservation grade mount board and I can’t find that many sources online but it’s clearly worth spending some time on.
Posting in a tube is good as I’ve received prints in those and they are pretty indestructible. I suppose that then gets rid of the packaging necessity, as you point out, and makes the whole packing task far easier.
It took me an age to change to hard backed envelopes for my cards as previously I was using recycled cardboard, cutting to size and then after enclosing the receipt and a thanks letter, wrapping the whole thing in brown paper. It didn’t cost me much in terms of £s but took an age, and to be honest I hated it. Then I bit the bullet and bought a few boxes of decent hard backed envelopes, changed what I do for the thanks and receipt and now it’s dead easy and so quick, and actually far more professional.
I have found that when I started out, I was so fixed on £s costs I forgot that sometimes just doing something differently even if it is a bit more in terms of initial cost, can save so much time and also really does look far more professional in the long run.
I’m trying to offer more things post free so if I can get a more efficient way of sending prints at a low cost, then that can only be good! (Off to research cardboard tubes… )
