Adapted from Kalinumba pattern, Timpeallan. Intended for use in double knitting. Rounds 1 and 2 single layer. Every stitch is doubled in round 3 to begin double knitting (this is not shown; only top layer is shown). Increases are done on both layers and stitches rearranged as necessary. (the secret here is adding the equivalent of 4 stitches per row--increase 24 stitches every 6 rows)
Shown with a cast-on count of 4 stitches.
