|My attempt was rather wonky|
The flat-felled seam is the type of seam used in making denim jeans, although it appears inside-out to reduce stitching. It is also used in traditional tipi construction.
|Mock fell right side|
|Mock fell wrong side (overlapping side is still raw - to be overlocked and stitched from right side.)|
What is the name for this? I called it a mock fell seam, perhaps based on nothing
My final version in the real jeans had the raw edge above overlocked and two rows of top stitching on the right side held it down beautifully. I can't show this as the jeans are not available just now.
It was a lot more difficult producing this post on my tablet than on my PC (I used to have a laptop - that was great) but on the positive side, I can do it anywhere.
