When I bought my Juki last year, it came with a $200 gift certificate from the dealer. It turns out that because my machine is Juki's break into the home quilting machine market, they don't yet have many specialty feet for it, other than the several that came with it.
I was interested, particularly, in a rolled hem stitch for doing things such as napkins. Well, lo & behold, when I searched their site, I found a Brother serger that has that function, plus several others, built into it for under $200. So I bought it with my gift certificate.
BUT, and this is a huge BUT: I've never used a serger before.
So, the question of the day is:
Do you use a serger (particularly as related to quilting), what functions do you use, and what advice can you give someone who's barely glanced at them before, but now has one sitting in the box by the backdoor... And I'm too intimidated to even unbox it!
