Children's Argyle-Patterned Vest

Hello, fellow knitting and crocheting enthusiasts.
My daughter would like to make an argyle-patterned vest for her 2-year-old son.
Unfortunately, I haven’t been able to find any patterns anywhere yet.
Does anyone have a pattern? I look forward to your reply.
Best regards

Der Begriff hat mir überhaupt nichts gesagt, aber Google sei Dank bin ich jetzt schlauer.
Ist das wieder modern? Ist voll an mir vorbei gelaufen.....

Meinst du so etwas?

Hi,
that’s exactly what I mean. The sweater vest—or is it a sweater?—is just so cute.
Do you have a pattern for it? I’d really appreciate it.
Best regards

The sweater vest is from a book

that’s on sale on Amazon. However, it’s written in English.

Thank you very much for the info. I’ll see if one of my “kids” can translate it.
Thanks.
