I recently had the pleasure of going to a baby shower for my friend M. In honor of her soon-to-be-born baby K, I knit a very fast sweater. This is one of my go-to patterns and it seems to be a hit for all the new moms.
I also knit the buttons into the sweater. It is safer than sewing them on as far as I am concerned. The only way the buttons will come off is if the sweater completely falls apart.
