Melt Cheddar Cheese For Nachos Nacho Cheese Sauce From Schools?

Nacho cheese sauce from schools? - melt cheddar cheese for nachos

So I was like the nachos, which you know to go to school until the middle / high school, you who, with cheese:]
I was wondering if anyone knew what they were? And how did they do?
I have tried velvitta [sp?], But the material is not easy, I worked with for years tossed with cheese, but I'm tired lol.
And cheddar cheese is too thick for me.

Yes, I am picky, but I like my nachos lol;]

But what someone could help me please?

I really want to know what they were and how they are used. Back in school, who had big pots of cheese, and including a pot of boiling water was, so I'm not sure whether you have a sauce or cheese and useHe founded his own account.
