For my king-sized snowball quilt I decided to echo the 2-inch squares than make up the nine patches in the center of the quilt in the border. That meant creating a border with 1,128 2-inch squares, and I didn’t pin a single one. The trick is using strip piecing and strategic pressing to save time without compromising on accuracy.
First I folded up the strips into squares to decide where I wanted each fabric for a balanced layout. Then I sewed the rows together in strip sets, pressing all the seams in one row in the same direction. Once the strip set is pieced you cross cut it to make rows.
I pressed each row in opposite directions, that way when you sew the rows together, the seams butt up next to each other and you don’t need pins to get a good join.
