Wow that is beautiful! I have tried the pretty puffy hat as well, a few days ago in fact. I was frustrated with it because it came out a bit to small. I am new to crocheting and don't know how to modify patterns to fit me. UGH such is my life :/ Would you mind writing a pattern for what you did? I find this hat gorgeous! Also how to do the bow. I would greatly appreciate it.
thankyou! i have made this hat in the past and had it come out too small as well. i can't remember exactly how i made mine bigger but i did mention in this post that i added a few extra increase rows at the back of the hat. my advice would be to follow the pattern and keep trying it on your head as you go, and keep adding increase rows until it feels comfortable, and then continue the pattern, and use less decrease rows near the end so it doesn't end up being too small again.
for the bow, i just did a chain long enough to make the length of bow i wanted, and did a bunch of rows back and forth until it looked tall enough. i crocheted a small rectangle and cinched it around the main piece and sewed it all together
