Ah yeah probably not. That would require looking shit up and I’m too lazy for that.

We do this not because it's easy, but because it looked easy when we started

Yeah, but you have to be careful not to get them too hot (since they'll melt)

you can use the “synthetic” setting on clothes irons for polyester and nylon (flags won’t really be made of a different plastic bc these are the cheapest reliable cloth alternatives). i think u can use higher heat on them than silk and satin. p sure the synthetic setting is half of the max heat

edit: just checked my clothes iron and the “nylon” setting is actually below the “silk” setting. regardless, u can use the “nylon” setting on a flag no problem as long as you use the steam often enough
