Welcome to Waterfall crochet, a method that introduces a way to get the
look of multiple mid-row color changes without all the hassle. No more
carrying the dropped color across the row, and no more mid-row color
changes. This new technique uses chain spaces to form a lattice to work
over. Colors are worked the entire row and color changes are only done
at the end of rows. For most projects, yarn is carried up the side and
worked over when making the border.
