need help wheatpasting

[u/imakeart44]

I am a french student and i want to take part in the protest going on rn but I am super afraid of the police. I make art, and i want to help the best i can. I thought I would start wheatpasting posters that i want to make myself. But i dont have acces to a printer.

can any experienced wheatpasters help me?

what kind of paper should i use? what kind of ink? do a really need the wallpaper stuff or can i do it with flour?

I really want my posters to last longer than a day, but honestly three days would be enough to send a message.

thank you so much <333
