Hi guys, I'm perplexed.

I am making my winch covers (great video by the way!). My circumference length is 36" which includes the 1" hem as indicated in the video. After I stitched the first two hem stitches, the circumference is now 35". What is happening? The stitches are set on the widest possible. The tension appears to be good based on a test of fabric. The Sunbrella is Medetarranean Blue Tweed (does the tweed make a difference?) I'm open to your suggestions.

For this project it will not affect me too much as I plan to leave the side hem open on the bottom and add a binding edge so that our jib sheet can lead from the winch while it is cleated.

Thanks, Linda

Hi Linda:
 
It sounds like you have a tension issue.  If both upper and lower tensions are too tight, you will lose about the amount of fabric you lost due to needle pucker.  Loosen both and things should get better.
 
Another trick that may help is to not backstitch and not cut the seams you have sewn.  You can milk out the excess pucker from the center of the seam out.  Then tie off the ends that you did not cut earlier.
 
I hope that this helps.

I am confused about "circumference length at 36" plus the 1" hem. Do you mean you added 1" for the side seam? Or are you talking about the hem added to the height for the bottom? If you did not add material for the side seam you will be short when the tube is sewn. Let me know if I can help further.

HI Matt, I think Dan got it, I have loosened the tensions on the bobbin and the tension knob. I think that is helping so far. Thanks.
