Very nice quality. As for the colors, chambray is a bit more towards the baby blue side and I would say brick is more of a muted terra cotta. But very nice colors for fall.
I made 2 cardigans and infinity scarves from these as gifts. The fabric was thinner than I expected for "brushed rib knit" but it washed and sewed beautifully with a little tweaking of my serger. The scarves did not drape like ITY does, but were nice for a winter scarf without the bulk. The choice of colors is amazing.
I go the plum vintage which was a bit more on the purple than plum side, but a lovely color that is still in my true summer palette. It was not really brushed; I was expecting something a bit thicker. I'm thinking to line it for a dressy top.
