I completed my first flat fell seam last night, joining a red stripe with a white stripe. Cutting evolved careful measurement and marking with a grease pencil under the watchful eye of Rachel Finn. We were able to tear the white denim down the full length of the two yards of fabric.
Things I learned:
-Selvage edge is what I would call the “factory” edge. You get two (one on either side of the bolt) and its a true straight line.
-Ripping fabric, you must tear evenly on both sides.
-For flat fell seams you have to iron the hem into place, otherwise there is no way to prevent the fabric from going all over the place.
