Rofur flags provides flags in 1/72 and 1/32. There`s also some advice for converting figures into flagbearers on their homepage. I don`t konow if it`s possible to order these products from outside of europe though.
Thanks for the advice.
Great idea with the tin foil, Mike.
My flags are drawn with both sides on the same sheet, with a "spine" area down the middle. You simply fold the flag over and glue the halfs together. I believe this is the usual method with commercial products, so there's really no reason why figure sets can't do this. They can always provide extra weapons for the flag bearer figure for those who don't want to bother with the flags.
