I love knit leaves! I put together stitch patterns from 3 different sources for this edging. There are 28 rows and the stitch count slowly increases from 20 to 39. Every row is a pattern row. The leaf tilt is made by increasing 1 background stitch on 1 side of the leaf and decreasing 1 background stitch on the other side of the leaf.
Skills needed: long-tail cast on, knit, purl, slip, yarn over, yarn over twice, knit front and back in 1 stitch (kfb), slip1-knit1-PSSO (SKP), knit 2 together, purl 2 together and bind off in knit stitch.

Gauge is not important in this pattern. Any block-able thread/yarn and size needles will work. Knit a swatch to check size and looks.

10 yards will make about 21 rows (1.6 inches) of border (unblocked) at 10 sts/inch and 12.5 rows/inch with #10 crochet cotton and U.S. #2 needles.
