Most new users don't bother reading our rules. Here's the one that is ignored almost immediately upon signup: DO NOT ASK FOR FANEDIT LINKS PUBLICLY. First, read the FAQ. Seriously. What you want is there. You can also send a message to the editor. If that doesn't work THEN post in the Trade & Request forum. Anywhere else and it will be deleted and an infraction will be issued.
If this is your first time here please read our FAQ and Rules pages. They have some useful information that will get us all off on the right foot. More details on our policies, especially our Own the Source rule are available here. If you do not understand any of these rules send a private message to one of our staff for further details.
Favorite Edit of the Year (FEOTY) 2020 Awards are here.
Not meaning this in a patronizing way at all, I think if you google and youtube search the particulars of what you're looking for you'll be able to find what works best for your current tools. Blender is a free option that I've used to create 3D texts. You can probably find templates for Harry Potter logos.
