Thanks for your advice so far!
(Yes, I just left the film on there for a bit of extra protection)
Actually for now I'm planning to put it in a simple sleeve that you use to put papers in binders!
In searching for sleeves, I came across
this little collection. (Someone on here also mentioned Esty). I'd be interested in your thoughts/insights/warnings...
Initially I'm drawn to the one that you put the Forma into horizontally, since it seems easier. The other one has huge good reviews tho...
I definitely don't want with a flap - it needs to be a one-move job!
