Wing wrinkles

[LVG2018]

We have reached the point in our construction process where we pull the wing envelopes into place. We have secured the fabric per Lockwood instructions on the first wing section; however, we have 3-4 small fabric wrinkles located where the fabric covers the rear spar at the wingtip bow. I am a perfectionist and hate to leave the fabric with any wrinkles (even though I have inspected several AirCams that have such wrinkles). Does anyone have a recommendation of what we might do to get rid of those wrinkles? We're ready to remove the fabric and try it again, but .....

I was told by Lockwood that they changed the wing material a few years ago and it's now stiffer than before, making it even harder to remove all the wrinkles. I doubt that starting over and pulling the fabric tighter would help, but don't know for sure. I was told by a very experienced builder that his wings never have any wrinkles. Though the wing fabric is pre-shrunk,he uses heat from an iron, as you did when covering the control surfaces. I experimented with that on mine and did get a few wrinkles to improve. I didn't want to ruin the fabric with too much heat so I didn't try too hard.
