one of my things I lean towards a typewriter font for things I have had forever and still use. and lot of places make them but, if you want to have something "classic go-to" maybe look for some sets with a classic font.a few companies have come out with some "label maker" looking single word block sets too so you can create the sentences.
that being said I have more sentiment set's than images because quirky fonts appeal to me.
the last few months I have been collecting these from like this one ( there are a few more)
