I offered to make my mom a hat for her upcoming birthday. She picked the yarn and pattern. I adapted it a smidgen, and really like how it turned out!
Here's the pattern (my addition and comments are in PURPLE, original pattern only has 19 rows:

MB = In same St (K1, P1) 3 times K1, pass 2nd, 3rd, 4th, 5th, 6th & 7th over 1st ST (refer to here if you need help with this, search under 'make bobble' for video)
