There are so many dresses out there now, Ann, with serged rolled hems, that I would almost recommend that route, unless you have a coverstitch machine that can make the hem without ripples. It used to be that a serged rolled hem did not look "finished", but that was before the deconstructed movement hit fashion. I've seen so many high end RTW lines with serged rolled hems on their tops and dresses over the past couple of years.
I'm going to keep watching this topic, because I'd love to read other's suggestions. This might lead to a real discovery about the perfect way to hem a 'heavy-ish" jersey skirt.
BTW, I tried to look up the pattern on the Butterick site, but came up empty. It must be OOP, so I can't see it. Waaah!
I'll just have to wait until you post the details on your 'blog, Ann.
