DFD (dreaded frontal droop) usually refers to cardigans whose front borders
hang below the level of the rest of the body.
This is remedied by knitting-up fewer border stitches when adding the
buttonband -- or, if the edge is knitted onto the the body as you go, you
can compensate by not knitting the border-sts every inch or so.
A DFD cardigan may be fixed after-the-fact by working EZ's Applied I-Cord up
the front, around the neck and down the other side. I-Cord is non-stretchy
and may be completely regulated by pick-up ration and gauge.
Short rows across the back are to prevent the DRU (Dreaded Riding Up).
