It'd be a waste to use those expensive materials just for practice. Use the practice materials I prepared to etch.<BR><font color = '#2478FF'>And remember: This is just a practice etching. You'll want to use the real thing, for actual applications.</font> There is nothing more I can teach you, <PCNAME>. You now know everything I know about how to create etchings. From now on, improving this skill is up to you. I hope you try hard and become a master of etching. Are you unclear on the process, <PCNAME>? Or are you just taking a break?
