Best Ideas for a Minecraft Bedrock Banner

Hi everyone,

I’ve seen a few servers and communities that use really creative minecraft bedrock Banner designs. I’d like to make one myself, but I’m not sure where to start. What’s the best size and design style for a banner in Bedrock edition?

Do you guys usually design it in-game or with graphic tools? Any examples or resources you can recommend would help me get started. I want something eye-catching but not too cluttered. Experienced players or server admins, your design tips would be really appreciated.

Thanks in advance.
