     Your "Therian symbol", the Theta Delta, is incorrectly drawn: The bar of Theta should have crossbars on the ends, while Delta's left face should be noticeably thinner than the other two. In any event, it doesn't appear to be very "common" or "well-liked", given this is the first I've seen of it.

     I think that's a pretty neat logo and I definitely prefer it to the Theta-Delta (which makes me think of dentists...and it's just an ugly symbol to me). I think that logo is cute and could be easily worn on a t-shirt though I think the hoof print needs resized.

     Hey psst would anyone be interested in buying a theta-delta (therian symbol thing) soft enamel pin if I custom ordered some? I'm baffled that they don't already exist

     Guten morgen, I appreciate the advice! Very smart… that could actually work, although, she may recognize the delta in the theta delta, since she watches those alpha männlich videos with my father…

使用する際の注意点

• As theta-delta does not have a Unicode character, the symbol is instead represented by ΘΔ or ASCII art via the combination of a hyphen-minus or dash with several combining characters: -⃝⃤, ⨺⃝.
