Thanks for all the info. I figured I would probably have to do this outside. What would be the lowest temperature ,60 deegrees? or warmer. Getting ready to dye my silk this weekend, and hope to have a few days of mild weather move in before long.I had no idea that the koverall would be that heavy or draw enough to warp the frame. I did a guillows se5a last year and used ultrakote for the covering . This was my first covering job. IT came out good, but I did have a issue with the wings warping. I used a jig and used more heat to take it back out. It was a major task. I have probably too much patience sometimes, but in the end ,everything was okay.Ended up at 8 oz. Not too bad with all the modifications, and additional wood I had to use to convert to electric. This dr I has been a bit more challenging., just wanted a more realistic covering. .
