BOBBLE HAT PATTERN
I used tiny amounts Drops Brushed Alpaca (which equates to a DK-weight mohair yarn) with 2.50mm knitting needles.
You'll also need either a tiny bell or a little felted ball for the top of the hat.



FYI:
W+Tk bring working yarn to the front of the work, slip next stitch knit-wise onto the RH needle, take working yarn to the back, slip the slipped stitch back onto the LH needle, turn the knitting = W+Tk (wrap and turn knit) 
W+Tp take working yarn to the back of the work, slip next stitch purl-wise onto the RH needle, bring working yarn to the front, slip the slipped stitch back onto the LH needle, turn the knitting = W+Tp (wrap and turn purl)
With the top of the hat colour cast on 12sts

Rows 9-10 Repeat last 8 rows from * to ** 3 times. Cast off.
Match the cast-off edge with the cast-on edge (WS together) and join the seam with mattress stitch.
For the Rim - with the second colour cast on 24sts
Rows 1-2 K1, p1 all around. Cast off in k1, p1 rib.
Join the cast-on edge of the rim to the row ends at the base of the hat. Turn the rim up and over the rim-to-hat seam.
Join the little bell or the pom-pom ball onto the point of the hat.
Slip the hat over the mouse's ears to make him lovely and cosy!
