Have made numerous projects by this designer.
All fabulous.

Pattern gauge:
15 st / 4” 3.5 mm hook

I had bulkier yarn and bigger hook, hence bigger stitches.
Worked 64 st around, 36 rows.
Made nose a little smaller, increased to 30 st + 2 rows.
Made the arms and legs a little bigger.
Fashioned a tail.
Added a carry handle, top center back.
