I have a busy day ahead (how many times can I use that excuse?) so this was a bit rushed. I want to practice it some more. I *need* to practice it some more. But here is the jist…
You can actually gather on your serger with our without a gathering foot, so long as you have a differential feed. There’s probably a trick if your serger isn’t a differential feed, but I don’t know anything about that. I mean, really, I barely know anything about what I’m about to show you.
And with that boost to your confidence in what I’m about to show you….
Start by cutting your fabric. The general idea is that you want the piece to be ruffled to be twice the length you’ll need at the end, plus five inches or so. You’ll most likely have to trim at the end to acheive the desired length, but better than having too little.
I didn’t get a picture of it, but you want your right and left needles to also be at the highest tension settings. On my machine it’s a nine. Your loopers should be set to an average setting, somewhere around a 4-5. You may have to do some resetting, so practice on a piece of similar scrap fabric first.
Now, if you DON’T have a gathering foot, turn your presser foot tension to the left, loosening it. A couple of turns should do it.
