first dragoncon!!

hello!! this year was my first ever dragoncon and actually first ever con in general :) i had so much fun with my sister and my dad we're all planning to go again next year. one of my goals next year is to get more ribbons so i'm wondering if anyone has any tips on where/how to get them. i'm also wondering how in the world i can find any marriott carpet merch because i learned about the cult and i think it's amazing and i want to be a part of it, and maybe i missed it at the vendors but i couldn't find any...
