All the details - Featherweight Cardigan, made in the smallest size, using The Loopy Ewe's Solid Series, on US 4's (3.25 mm). I did all the edgings in the Simple Cable Rib from Knitting On The Edge (adjusting stitch counts to fit the repeats as necessary). Using the fingering weight yarn makes the sweater more opaque than the laceweight, but you also lose a bit of the drape and airy-ness of the sweater.
I'm sure this isn't the last time I'll make a Featherweight Cardigan and I know I'll use this yarn again as well. I might have to try a Featherweight made from fingering weight yarn with a collar of Kid Silk Haze, like I mentioned a couple of weeks ago.
