From Dorothy Reade's "Decorative Panel Designs". In her instructions Dorothy Reade uses kbf rather than kfb. The k5tog is to be worked as follows: k2togtbl, k3tog, pass the first stitch over the second. The double increase in row 1 is to be worked kbfb. Also k2togtbl was Dorothy Reade's preferred method of working a left-sloping decrease. In the swatch I've used all of her methods.
There is an error in row 23 of the chart which I have corrected.
Shown with a cast-on count of 25 stitches.
