Ripples radiate from the calm centre of this semicircular lace shawl, the initial smooth-sailing stitches giving way to broken, stormy seas at the outer edge. Blue Bang is constructed from the centre out according to Fibonacci’s sequence, giving it an aesthetically pleasing rhythm accentuated by the stitch patterns. ITO Gima 8.5, an unusual cotton yarn with a flat, ribbon-like form, creates a crisp texture that adds to the airy character. Buy the pattern here.
