Errr... uhhh... They were made with a brand spankin' new ruffler attachment on my sewing machine.
I had no idea this existed, and now I can't believe I ever made a ruffle without one. Thanks to a suggestion from The Infamous Pam Kitty Morning, I went ahead and bought one of these sweet babies. And I just made 350 inches of ruffle for a project in about 5 minutes.
Mine has three settings for spacing the ruffles, and I haven't tried it yet, but apparently you can create your ruffle, and attach it all in one fell swoop too.
So... ahem... if a ruffle-less project ceases to exist around here, you'll know why.
(((Since I know you now have to have one... To get one for your machine, contact the store you got your sewing machine from or the manufacturer.)))
