That is so exciting, Alane!!
Just off the cuff:
ETSY
Definitely fill up all your featured item spots.
Maybe in the welcome section give a little shout out / reference to the video. I would make the first sentence something like, "Just wanted to say hello to all the MrArturoTrejo watchers ... I myself am a fan... etc."
On the monkey hat listing I would also make mention of the youtube video and maybe even share the link in the description.
