Welcome to the Quilting Board!

The way I was taught to sew long strips is to hold the top strip up off the bottom strip until it goes under the needle. This feeds the top strip the same as the bottom and keeps the edges matched almost automatically. If the strip is long enough I toss it over my shoulder (jelly roll race quilt sewing).
Got fabric?
I will keep pinning as well.
That is the way we held our long seams at the sewing factory.
i go both ways on this too, pin or not, but thank you for sharing this tip will try it soon
we can make our plans but the out come is in god,s hands nellie diaz
To some extent, I think it depends on the specific sewing machine also. I have seen machines that seem to feed very unevenly, with the feed dogs pushing through much more fabric than the presser foot allows. My Bernina, even though it does not have the accufeed feature (built-in walking foot), seems to feed very evenly. That may be why I've never had much of a problem with uneven feeding of strips or "bending" of long strips from stretched fabric.
So, the two-handed strip feed may work better on some machines than others. It may not all be user-dependent!
I found this demo on how to do this, but you have to watch closely what she does with her right hand.

I have enjoyed reading all the comments this has brought. It was interesting to find out this is an "industrial" way of sewing long pieces together.
The lady who told us about this just off handedly said "you should be doing all your seams like this"--that's when I realized I wanted to update my methods.
God Bless,
