21 (28, 35)“ bust circumference. You will not need all the yardage listed to make this. One skein each of three colors of the recommended yarn to make the smallest size will leave lots of leftovers of two of the colors.

Valentina Devine designed this darling (yet chic!) child’s sweater to match her Boho Blocks cardigan in the fall 2006 issue of Interweave Crochet (available at www.interweavestore.com). The pullover is made from strips of square motifs that are slip-stitched together, with a clever underarm gusset created by folding one motif in half. holding two strands of a variegated yarn together creates a rich marled look—play with colors to make your own unique sweater!
