Hi
since my last post I have advanced a bit with the pressure fan, but still need a bit of advice. Here is a picture of the best pressure fan I can do at the moment.

I need some advice on getting it wider (my thumb always gets stuck halfway through the fan) and it always turns out lop sided with the top either sticking out to much (as it is in this photo) or the fan basically flat with little curve and the cards very densely packed. Here is a link to the tutorial I learnt it from. (I have been practising around 3 weeks to get it to the stage it is now, and would like to be able to get it bigger)

Any help/ advice will be greatly received.
