If one had ever stretched Spandex to a really tight pull, they would see how the weave of the Fabric will distort as it opens up. This creates larger spaces in the weave that can be / are visible during projection, and even create a degree of Morie patterning in areas.
My experience has allowed me to use lengths that are just under the length of the frame, and then stretch about 6-8" on each side (end)before stapling. That does amount to being 12"-16" stretch.
However in this particular case, we are talking about a 14" difference between the actual length of the cloth and the Frame. Add another 12" to that and the total amount of stretch is 26".
Is that too much? Only a visual observence can speak for that, and I'll tell ya sumpthin'...the time to find out that your stretching it too much is not after you have effected about 30-40% of the job. Also, stretching the fabric evenly is far more difficult under the amount of pull we are talking about being necessary. I know.....having been there, done that.
Now when one is attempting such on their own, and wants to save cash, the end results can be (ie: might be
) accepted as a risk worth taking. Not so in this case. I would rather myself to observe the degree of pull needed to effect a taunt surface.....but no more, and sacrifice the overage amount in trimming, than try to force a too small piece to cover a too large frame, and have both a visible fabric pattern distortion be created, and also risk having the material pull out from, tear off the staples.
I don't want to talk overly about profit & loss here, but hey, by the very nature of such I'm not into spending any more than necessary any more than any other DIY'er, and after all, everything I do, both Visual and Aurally is all DIY. In this instance I'm taking a $89.00 hit***
on behalf of my customer, and my own time possibly wasted on a poor result. *** 1st order cost $54.90 for 2-Day delivery
...and having my Guy make note how I did not hesitate one instant to make it right? Priceless.

Awww....don't even. What's another $9.00 compared to the risk?
