That would be choosing....wisely. Even when there are 40% off sales like are now going on at JoAnn Stores, you'd be hard pressed to find Triple Plush Black "Dress" Velvet for anything under $12.00 yard.
One more question - in the original post, MM says that he ripped the 3.25" moulding down to 2.5. Is there a particular reason for that? I'm going to build a 120" screen and am thinking of leaving the border at 3.25". My 60" plasma has a 2" border so I don't think 3.25" would be disproportionate for a 120" screen. Is it just personal preference or is the another factor to consider?
Mostly personal preference. Truth is, the larger the screen is, the less it matters. But the smaller a screen....that can make a difference. In the case I posted about 2.5" trim, the screen was only going to be 84" diagonal.
Nowadays, what with the "Ultra Thin Bezel Trim' look being considered as "way cool', thinner (skinnier) stock would be the 2.25" trim, but I have also wrapped 1-3/4" pieces for 120"+ Screens because that is what was wanted. And when "inserting" Trim within a Painted Wood "Picture Frame", skinny is the only way to go.
So....design criteria and / or personal preference both play important parts in choosing Screen trim dimensions.
Wide Black Trim has always served as a "reference Black" for the content's Black levels, and can fool the eye into thinking the Blacks within the image are darker than they really are. Then there is the "Over spill" issue. But super high Contrast levels on today's PJs, and better, more precise Formatting have greatly reduced the need for W---I---D---E Trim. But as previously stated, on larger Screens, it not only helps everything look better within the image, it also adds distinction outside the Image.
And lemmie tell ya sumpthin......ain't no one ever "Ooooh'ed" & "Aaaaahh'ed" when they got up close and personal and touched Black Velor.
