I try not to skid in order to save my tires.

Use a brake.

However, if the OP wants to learn how just to learn how, he should reduce his gear inches to 72 or below and lead the technique by pulling up on the forward leg, instead of locking the trailing leg and then pulling up on the forward leg.
In your mind, initiate the movement with the thought of hitting the handlebar with your knee and then your hips; your trailing leg will do the right thing.

I brake by back pedaling, and I inadvertently skid on a regular basis.
In my humble opinion, once the skid begins, the bike skids further than it would have if held just at the edge of skidding.
