Flags
Members of the SCA are allowed to have flags of their arms, all according to rank of course. As many people are of knightly rank or higher the flags often take the shape of banners (oblong), pennons (three cornered) and standards (large extended triangles with a swallow tail). Pennants are smaller versions of the standard and they usually end in one point. Kingdoms and principalities also show hanging banners of the gonfanon type, that is: with three or more slips.
Until recently these SCA flags were fixed to staffs with a series of cloth loops, giving the edges an embattled look. This is pure Hollywood; in medieval sources you would never find such a fixing method. The flags had a tunnel at the staff end through which it was passed, and sometimes nailed as well. Or there was a series of laces or cloth bands which were tied around the staff.
While banners are repetitions of the arms on cloth and the gonfanon partly, other flags can be added on. Besides the arms or its components, there could be badges, mottoes or livery colours on them. This could make for quite a lot of variation in the heraldic displays at a court or a tournament. Badges and livery colours, including certain elements from the arms, could be used for other decoration as well. For instance wall hangings, rugs, curtains, coverlets, cushions and decorative borders could contain heraldry.
Let's take the arms om Giuliana la Gazza. Left the official West Kingdom arms, right my design. A banner of these arms would look like this:
And pennants could look both of these ways. It's a bit like playing with shapes and colours and it is highly decorative.
And these charges and colours can be used to every purpose that you want. I could make you designs for everything neccessary. I do these in digital format and in any size you want so you can make your own totally period flags from it.
