I’M MASC

A closer look at said seams:

these are what i know as "zipper seams," and i use a specific variant (??) where you work in back loops (normal) but insert the hook in reverse direction (from back to front), like you would a mattress stitch (??). this last bit puts a funny twist in those back loops that shores up the gauge considerably. (oh, and in the corner sts, which are hdcs in the border treatment I use for seaming, you should work in back loops plus that weird supernumerary loop that hdcs get. This keeps the intersections from getting ugly — I forgot to do it here and had to do a little extra darning, which who cares it's fine).
