Here are the modifications for making a Beekeeper's Quilt hexipuff with Skinny Bugga! This yarn was originally made by Sanguine Gryphon, but is now sold by its offshoot company Cephalopod Yarns. It's a fingering weight merino/cashmere/nylon (80/10/10).
This results in a 3" diameter puff.
Cast on 11 stitches per needle (22 stitches total) on US size 3 (3.25mm) needles.
Increase per pattern to 21 stitches per needle.
Add one extra row of plain knitting after the 2nd increase and again after the 3rd decrease (when there are 15 stitches per needle).
Decrease per pattern to 11 stitches per needle.
Bind off as per pattern.
