This is my first completed granny square!!
I used this pattern, but had to make a few alterations to adhere to the rules of the challenge

I used a magic ring instead of a regular circle, and omitted the last round, so that it would be closer to 4"
I love it!!
My advice: Believe in yourself, believe in someone else, let someone believe in you.
