Dear Sandy et al, just read latest update regarding Runes - glad u've gone for practical option with Runes as Cards.
What size will they be?
Please please please 1. design them to fit with standard or small sleeves 2. Design insert to hold sleeved cards (and nonsleeved, if u must! Lol)
Ultra-pro have amazing new sleeves called Pro-matte, which are easy to shuffle AND don't slide around AND 1 colour option is transparent, so the awesome art on back of card is still visible. I'm using them for most of my boardgames now. HOWEVER they only come in "standard" and "small" sizes.
So I humbly request that the runes are designed to fit in either of these. Of course if the runes are even smaller than this, please design one side to fit in either of these sleeves. Then we can just trim the excess off.
AND DON'T FORGET THE INSERT ALLOWING SLEEVED CARDS PLEASE (I'm looking at you, Tyrants of the underdark! )
