Knit with Rauma Strikkegarn. I love this snowflake top and striped sole. This is the easiest colorwork heel/sole to knit .
Size up a needle-size from gauge and this slipper would make a US Women’s 5-6.5.

Anders is included in my Norsknit Ebook

Felted Gauge
Lightly felted 28 stitches and 24 rows = 4 inches or 10 cm

Note: Pay attention to your gauge and use whatever size needle you need to knit 24 stitches and 24 rows for 4 inches. While teaching a class on these slippers, I have seen knitters use needles as small as a US 2 and as large as a US 5.
