I hate to say it, but ð is likely the wrong character for that sound, you’d be better with þ. Ð is never used at the start of a word, and þ has a long history in English as being used in abbrieviations for words like “the” and “that” (see “uses” in this article https://en.m.wikipedia.org/wiki/Thorn_(letter)). Your use of ð is correct for the Icelandic use of the sound, though, so I absolutely see where you’re coming from.
Unless you’re using the IPA ð, in which case ignore me.
(sorry for the rant, I used to be very passionate about returning þ to common use in English)
