Question about making kippahs for bat mitzvah

Hi, I need help with a question about embroidering the dates on the kippahs I’m making for my cousin’s bat mitzvah. Is it ok to use English dates/letters? My sewing machine doesn’t have Hebrew script.

Would it be a faux pas to embroider it in English? I know there’s a Hebrew date.

I’d ask her, but I want the embroidery to be a surprise.
