Cotton yarn makes the two sleeveless tops in Casual Cottons perfect for summer. Sleeveless Pullover features a button placket neckline and a pattern of lacy diamonds near the bottom ribbing. Zig Zag Pullover is a drop-shoulder sleeveless top with the look of cap sleeves; it has an allover pattern of textured zig zag stripes and a mock cable pattern in the bottom ribbing and collar. Both are knitted using 100% Cotton Medium/Worsted Weight yarn and straight knitting needles in Sizes 4 (3.50 mm) and 7 (4.50 mm); Zig Zag Pullover also uses a 24" circular needle in Size 4 (3.50 mm) to make the collar. Patterns are for three sizes: Small (30"-32" bust), Medium (34"-36"), and Large (38"-40").
