You can hold your pencil the same way as your pen – between the thumb and the first two fingers (generally). This way, your hand won’t tire because of the perfect balance you are able to achieve with this comfortable grip.
For light, feathery lines try holding the pencil lightly and half-way up the shaft.
For rich firm effects hold the pencil firmly and lower on the shaft, rubbing the lead to and fro without removing the point from the paper.
For small or detailed illustrations, you might like to hold the pencil lower still.
Hold the pencil in a way that suits you
