No no, the glass is indeed way more expensive than acrylic. Like I said the guy said that for my Tali giclee, it would be $550 to get her all framed up using 2 lower entry mats, a lower entry frame, and masterpiece acrylic. Had I gone with masterpiece glass, it would have been over $1,000!
I should also clear up though, that my Tali giclee is the C&B beast that measures in at a staggering 41"x26"(inches)! It's not the smaller 18x24" litho from Treehouse.
I should also note that my The Team litho (the Treehouse behemoth) was farmed using a higher end frame and 2 higher end mats. The frame is made of -or wrapped in- faux leather, and the larger mat is made of suede, whilst the smaller mat is made of faux leather. That's partly why it ended up being somewhere in the $350 range, if memory serves.
Regardless, in my experience, custom framing is almost always an expensive endevour. I've gone to mom and pop shops, as well as to the bigger chains, and it's just never fun for the ol' wallet.
Here's my baby for reference. You can kind of see that the mat is made of suede and that the frame has that faux leather texture:
I know it's difficult to tell, but the piece is massive!
