Answer:1. Rules of thumb:
> When transporting your tools and drawing, carefully put your media away in cases. Charcoal is very volatile and drops its pigments on your paper and on the table, not to mention graphite pencils, color pencils, and pastels, which roll, fall, and break.
2. caring for your tools with leads > The leads in graphite pencils and color pencils often break, even inside their wood casings. Protect them from shocks. When working with several pencils at once, avoid constantly laying them down and picking them up again. It's better to hold them in a hand that isn't drawing.
3. clean your erasers
> Clean classical erasers by rubbing them with a cotton cloth or washing them in soapy water (don't forget to dry them before using them).
4. fix your media >Charcoal, dry sanguine and chalk are all unstable media. To preserve your creations, fix them on paper.
