Luma is a lovely blend of merino wool, organic cotton, silk + linen; just the thing for 3-season wear. The fabric is soft and drapey, warm yet breathable, making for a project that's cool to knit in the summer, but you can wear in warm and cold weather alike.
To make the Slipped Stitch Vest, you'll need:
6 (7) skeins of Luma
US6 40-inch circular needles
Slipped Stitch Vest pattern
