help sewing one inch welt to a pillow?

I am making silk pillows with one inch silk welt. It always twists. Any tips on how to apply large welt without it twisting?

Are you cutting your welt strips on the bias? The extra flexiblity of bias-cut strips may make them less likely to twist.

Could whatever you're using for a welt cord be increasing the tendency to twist?

Beyond that, I'm not quite sure what you mean by "one inch welt" - one inch in diameter? In circumference?

In the meantime, some of the tips in this Answer may be helpful (though some won't apply).
