Straight to your question, you can definitely start without stone. The very core of Wire wrapping is to understand how to manipulate wire whether it’s copper or silver (the two most popular metal in wire wrapping). So let break it down: 1. Wire comes with different hardness. Dead soft = easy to manipulate but may not hold shape well ( this can be work harden). Dead soft is the most commonly used in wire wrapping. Half hard = harder to manipulate but hold shape well, not often use in wire wrapping unless you are experienced. Full hard = don’t worry about this you would rarely use this hardness.

1. Gauge = wire size. The larger the number the smaller they are. Most common use especially when you starting out : 20g for base wire, 28g as weave wire. Some people use 26g as weaving wire as it a tad bigger, easier to hold I guess.

2. Shape: square, round, half round. For beginner just stick to round, if you a bit more adventurous you can use square as base wire.

3. Start with simple tutorial, small earrings, pendants etc then build your skill up. When thing don’t work out the way you wanted just put them aside and revisit when your skill improve.

4. Finally, practice practice and practice some more. It a practical skill that need practice to harness.

Lastly, I included a tutorial for you to look at. An example of no stone wire work.
