US 7 (4.5 mm) 16” (40 cm) circular needle

US 8 (5.0 mm) 16” (40 cm) circular needle

Just one US 8 (5.0 mm) straight needle (for 3-needle bind off)

Stitch marker

Darning needle

Approximately 150 yards of worsted weight yarn


19-20 stitches per 4 inches (10 cm)

Note: Adjust needle size to get gauge


S/M: for 21” (53.3 cm) head measurement (18.5” or 47 cm finished circumference)

M/L: for 23” (58.4 cm) head measurement (21” or 53.3 finished circumference)


Cast on 92 (100) stitches on smaller circular needle and join round. Place marker and knit 9 rounds in stockinette stitch.

At marker, switch to larger circular needle and continue in stockinette stitch until hat measures 8 inches from cast on edge.

Starting at marker (which can be removed at this point), slip 46 (50) stitches onto the smaller circular needle, turn hat inside out and prepare to close the top of the hat. (You will now have 46 (50) stitches on each of the circular needles and will be ready for the 3-Needle Bind Off.)

3-Needle Bind Off

In this technique, you will begin working with the points on the right of the circulars and knit and bind off across the row so that you end up at the points on the left of the circulars with only one stitch remaining.

With hat inside out, arrange the circular needles parallel to each other (with their points facing right and left).

Move the yarn behind the needle in back, insert the straight needle knitwise through the first stitch on the needle in front and knitwise through the first stitch on the needle in back and knit the two stitches together. (You will have made one stitch on your straight needle.)

Repeat this motion again to make another stitch on your straight needle, then leapfrog the first stitch you made over this new stitch, binding one stitch off. Continue making a new stitch and leapfrogging the old stitch on your straight needle until you have one stitch remaining, then cut your yarn, thread it through and weave in the end.

Turn hat right-side out, pop it on your head and fold corners down to make your Dobby Ears!
