or this one:

also i've had decent luck with the old warhammer orc banner. the flat squarish one that has 2 small rents in it. i have one like that that i've painted up for my tzeentch army which looks nice and if you can find some thin hollow tubing (best i found is actually from lollipops with the whistle) which fits right over the banner poles from the sm or csm banner men. (mine is on one of the older DA robed bannerman).
