First Glass Box Pic

What did you use to stick down the fabric to the fiberglass?

you mean fabric to the mdf?  if so i hot glued it.  i like that better imo than staples.  if you mean fiberglass to fabric then just soaed the fabric in resin.  i think i may have misunderstood your question

Well, is the face of the box finished with fabric? Looks like vinyl from the picture. So, I was asking what you used to flatten the fabric to the front, after it was stretched over it. Like if you put an adhesive to make sure it would follow the curves perfectly.

If it is a paint finish and it just looks like vinyl in the picture then nevermind. heh.
