Don't use worksheets but ensure she is starting in the correct place for each letter and making the correct sequence of movements in the right direction.
You can practise forming letters anywhere
on the kitchen work top in salt or flour
with shaving foam in the bath
outdoors with a big brush and clean water
and of course with a pen on paper
make it fun but stop her if she's doing it wrong
I do very dramatic groans and squeals in handwriting practise in class and have been known to jump up and down when children produce "humps" instead of n or m (I think they sometimes do it to get me jumping)
so even when I'm correcting we laugh
I get my children to repeat a little "mantra" describing what they are doing when they write
write it in the salt with index finger then on a cold surface with the same finger then with eyes closed and finally on lined paper with a soft sharp pencil
