OK, I think that is the answer I was looking for. I have the ruffler foot, so I ruffle the longest tier, and then sew it onto the next shorter tier. That makes sense! Sorry I guess I didn't ask the question the right way.
If I make a ruffle on the bottom of a skirt, do I need to use one continuous piece of fabric? I think the answer is yes, but I want to make sure. Thanks for everyone's help!
I have looked everywhere for that fabric. Where did you get it? I love it!
