I haven’t done much with scarves and hand bags. PreCOVID I often wore scarves around my neck to my office. If I became hot, I would fold it in a strip, like a pony tail scarf and do a simple knot on my bag. That was mostly to make sure I didn’t leave it behind somewhere. And yup, it often looked cute!
I think your starting point would be to fold it lengthwise into a strip. Maybe a search on YouTube? And the different bag forums? There are probably many threads on scarves and handbags already started in the different forums. Also do a search using twilly. Also ask when you see something you like. People here can be very generous with info, good luck!
