This really sucks

Five inches of 366 stitches per row on US3s is killing me. I've done about 3 1/4 inches. It's the freaking knitting doldrums.
It's a good thing this arrived yesterday!

This is number one on the list after Fleur. Nothing outlandish, just a simple silhouette with a waistline. I think I'll knit it in navy. And yes, more stockinette! But this is different somehow.
