Umbra & Penumbra is a top-down pullover exploring the effects of light and dark in an “ombré” style. Typically used to describe celestial shadows (such as solar eclipses), umbra and penumbra refer to two parts of a shadow and may also be used to describe levels of darkness.

Featuring a mock turtleneck, Umbra & Penumbra is worked seamlessly in a slip-stitch pattern, using the effects of color dominance to showcase color gradients. In using two colors for each stripe of the slip-stitch pattern, one color will be dominant (or, more pronounced) and by alternating which yarn is dominant, more color gradients may be achieved in subsequent stripes.

Pattern Difficulty: Advanced Beginner/Intermediate. Techniques Include: slip stitches, increases and decreases, knitting in the round.

Short rows are worked at the yoke and shaping at the waist to create a better fit. The slip-stitch pattern produces a stretchy fabric that is well-suited to both a relaxed fit and a more fitted fit. The model in these photos is wearing the sweater with 2” of positive ease, but zero ease or a bit of negative ease would flatter as well, depending on the preference of the wearer.

The pattern calls for six colors of yarn, resulting in 16 gradient stripes. Combining a sport weight yarn and the slip-stitch pattern, the fabric is lofty without being bulky or dense. Wool of the Andes is a great workhorse yarn that will keep you warm without needing special treatment. As a pullover, Umbra & Penumbra would be an ideal sweater for a fall hiking and camping trip as well as a cozy fireside sweater.
