Hello, I have a question about shirring. How do you do it?! haha. I have a sewing machine but no shirring or gathering foot and I'm not getting one. I THINK there is such a thing as shirring tape you can use to do it by hand???! Only thing is, I can't find any good detailed instructions online on how to do it. I've had this explanation for it "One of the ways to do it is to zigzag over an elastic thread and pull up the thread. Do a bunch of rows of this and then pull up the threads all at once." I don't know maybe its me but I just don't understand those instructions clearly. If anyone can pleeeeease give me some good instructions I would greatly appreciate it! Thank you!
