You did an excellent job! I love how the edging mimics the cables. Is that edging knitted or crocheted?
What I hate more than doing seams, is working on DPNs.
I have one important suggestion:
On the front edges of the bonnet, where the tie comes through the beading, cinch up the tie just a tad and then bring each side of the tie through the last opening again to secure it, so it can never get accidentally tighten too much around baby's neck.
