I would agree with beeno about using bridge sized cards.
When I first started I thought that due to the size of my small hands that I would use bridge sized cards.
As I got more advanced and started wanting to switch to gaff decks mid performance or wished to use a gaff card I realised that getting bridged sized versions far more difficult if impossible.
When I switched to poker sized I struggled and had to almost re-learn alot of slieghts over.
I would say persevere with poker sized and as said above adapt the moves to suit your hand.
Seems this topic is well covered. Only thing I can think of is, think Rene Levand. He only has one hand, and it looks pretty small yet the mans card work is phenominal.
