Trinketer is a relatively uncommon word, and as such, there are not many synonyms available in common usage. One word that could be substituted for trinketer is trinket-maker, although this does not convey the same sense of frivolity or lightheartedness that trinketer does. Other potential synonyms might include bauble-designer, knickknack-creator, or gewgaw-craftsman, although again, these all lack the playful connotations of trinketer. Ultimately, trinketer is a unique and memorable word with a distinct meaning, and while there may be alternative phrases that could be substituted in certain contexts, it remains a useful and evocative term in its own right.
