Heartleaf, a free knitting pattern from Knitty.com.
INTRODUCTION
Heartleaf
by Kayla Baldwin
![]()
Inspired by the many pothos plants around my home, this sock is leafy and vibrant. It features twisted stitches resembling vines and stems, and leaf lace featuring a centered leaf. Influenced by Japanese knitting involving simple decreases and twisted stitches forming a complex all over pattern, it ends with a beautifully finished toe that evokes vines growing out of the soil.
