Here is what the ruffled trim looks like:
Ruffled trim for Sherbet Striped English Gown
I used 24 mm wide gros grain ribbon in purple and 12 mm gros grain in green. I had to sew them together before ruffling them because, it didn’t stay straight otherwise. The result is a ruffled stripped trim to match the dress fabric.
By the way, if you are interested in getting specialty feet for your sewing machine, I suggest you shop around. Originally, I had gone to a local Singer store (the one situated in Centre Laval), hoping to get the actual Singer part, but I they had the worst customer service I have ever seen. When I entered the store, an oldish (I wouldn’t dare to guess her age – I’m usually not that great at guessing people’s age), overweight woman (I'm being descriptive, not judgemental) was sitting in front of the counter, texting. When she realised I wasn’t leaving, after about 3 seconds, she sighed, straitened up, and ask in an annoyed tone if she could help me. I happily explained I wanted a ruffler foot. “Ruffler? Ruffler! What the heck is that” she barked. She then rose with difficulty, limped to the back of the counter, grabbed a ruffler foot from a display on the wall and threw it on the counter. “Is that it?”. I looked at it for a minute: it wasn’t a Singer brand, and the price was 45.99$ CAD (with Québec taxes, it would have cost me 51.91$ CAD). I guess I stared at it too long, because the lady said “Well are you going to take it?”, to which I answered politely that I was going to keep on shopping because I had seen some for much less. On this she concluded “Huh! Good luck!”.
I got mine for 20.75$ CAD, shipping included. The eBay store I bought it from, Gone Sewing Company, is well organized and I easily found what type would fit on my machine (thanks to good illustrations and exhaustive Model number lists). I received my part within 10 days, which is also quite decent. If you want to buy sewing machine parts of specialty feet, I recommend that seller.
As for the Singer store lady… well I have nothing polite to say, so I’ll leave it at that.
