Welcome, @petra! 
I’m Katerina.
Your challenge entries can be in whatever format you like, with as much or as little content as you like! 
It’s also totally okay to post it as a new thread like this, or as a post under the challenge post: :witch_pentacle: Weekly Witchy CHALLENGE - Finding Your Witchy Talents
Your collection is lovely, by the way!
I’ve added the challenge-entry tag to your post to ensure the mods see it when they get around to checking everyone’s entries to give us all the badges.
