Question about quantities

Hi Everyone
I’m new to all this so was wondering about quantities to add on each listing. I make cards, individually, and other papercrafts, which I can make to order (although I do have each ready) and at present have most items listed as a single. Do you think people are put off by there being only one? I appreciate with most crafts there is only one and that’s brilliant! I know in a b&m shop sometimes people are loathed to ‘take the last one’ even though you’re trying to sell it! Just thought I’d ask those who’ve been here much longer with more experience.
Blessings
Jan
