[TheForge] Glass question

[Steve Smith]

I'm starting to draw up a glass topped table, which I've never made 
before (any tips will be very helpful).

What I'm wondering is if glass tops come in standard sizes, or if they 
will cut to size as needed. If the tops are standard sizes, then I have 
to talk to a glass shop right away before get started. It seems like it 
shouldn't be expensive to get a piece custom sized, but what do I know 
about it?

Thanks,
Steve
