Every time you pick her up give her a small treat, slice of carrot, cucumber, parsley etc. Even if she never grows to like being picked up if the result is food it will become more acceptable. I move mine around in their pet carrier or a hidey, they have got used to this now and just jump in (I place it in the cage), once they are out of the cage in the carrier it's easy to pick them up - no stressful chasing round the cage. I find it's easier to trim long haired piggies if there is someone else to hold them still. Use food as a bribe and only cut off as much as you can before they get too fidgety. You'll have a lopsided pig for a few days but that's better than an accident. I put mine on the floor on newspaper with a pile of food if no one is holding them.
