Let's try this again. Sorry for the poor lighting, and the tiny hands that are "helping" me in this one. But at least I got it done right this time, eh?
As always, transfer your pattern markings to your fabric.
Snip ends of tuck lines
If desired, mark the stitch line. I didn't have a pattern, as usual, so I made my tucks' stitchlines about 2 inches. Just for fun.
Fold your fabric, right sides facing, so that the snips line up for the tuck you're working on.
Starting at snip, backstitch and sew the length of the stitchline
With needle down, at end of stitchline, turn toward tuck allowance and sew across, completing the tuck
repeat for all tucks
Press in the same direction as you sewed, but don't press beyond the tucks' stitchlines. Let the fabric just open up from there on.
The Book says: "Release tucks are used to control fullnes and then release it at a desired point, such as at the bust or hips."
