A note of encouragement to those who have smaller hands. The size of the hands isn’t really an issue, big hands have problems too. It just takes time for your fingers to learn to stretch and find the right grip. You’ll be fine.
Your fingers are going to get sore at first, but they WILL stop hurting after a while. Practice in short bursts, a few minutes at a time, then come back half an hour later. Golden rule – little and often practise works best.
