Scrappy Rainbow String Quilt Top - the tutorial I used to construct the string blocks over at Film in the Fridge. Or, a similar method is shown in Elizabeth Hartman's book, Practical Guide to Patchwork, under the quilt "Valentine".
LOVE the color palette. This is one of my favorite go-to quilt patterns for a quick baby quilt. It works really well to show off a main 'focus' print contrasting with a variety of prints in scrappy four-patch blocks.
