Zylphia is worked bottom up, in the round, with a modifed circular yoke decreases, out of Sanguine Grphon Eidos. It actually works up surprisingly fast; the lace patterns are easily memorized and the stretches of stockinette stitch between the lace panels fly by. I’ve fallen in love with the honey bee lace. Sooner or later I’ll do a cowl pattern with it as well.
Emily is a bit more of a challenge with the inset lace panels. The panels are worked like intarsia. Although technically speaking the portion including the inset panels is worked flat, the ends of each row are joined when you turn to work the wrong side (thus “modified intarsia in the round”). Once the inset panels are finished, the skirt is worked traditionally in the round. The lower lace ‘flounce’ is worked in the round and is joined to the main body of the skirt using k2togs (sort of like a 3 needle bind off, without the binding off).
I think all the Steampunk patterns are just lovely.
