Beautiful pattern worked up well with some revisions: I opted to ignore Partial Blocks 3 (yellow) and 4 (green) completely, since the technique did not work up favorably, it just caused a ripple rather than a slope as with Partial blocks 1 & 2.

The pines were worked as plain blocks throughout with no shaping devices. Saved time and cramping for a prodigiously finger-cramping opus.

Made from a repurposed Ralph Lauren cotton sweater.
