I do bright colors for babies. They get past the black and white atage in something like 6 weeks.
I am sending along pix 2 of my really fast, but joyful baby quilts. Whenever possible, I put the fabric to work, with minimal sewing but lots of bright color and strong shapes. Many of the standard old fashioned star patterns work well as oversized blocks.
The second was a quilt in an afternoon, cut sewn pinned, birthed and quilted.
