INTRODUCTION
Mountain Forest

by Susan Mills Knits
![]()
Knit from the bottom up, the colorwork section can be knit in a gradation of colors. I wanted to use as many colors as possible from my large stash of Lettlopi odd skeins and partial skeins. Alternately, you can use one contrasting color for the colowork for a bold contrast.

PATTERN NOTES
[Knitty's list of standard abbreviations and techniques can be found here.]
Construction method: The body of this pullover is worked seamlessly in the round from the hem up to underarms. Sleeves are worked in the round from cuff to underarms. Body and sleeves are then joined and yoke is worked in the round to neck ribbing.
Colorwork: It may be necessary to use a larger needle while knitting the stranded colorwork in order to maintain the same gauge throughout both the solid color and colorwork section.
