Custom hanging banners

So 2 ideas in 1.

1- dungeon master pledges get the opportunity to have the same style of kickstarter custom banner but on hanging banners.

2- same as idea one but also a customisation menu for other pledge levels and other players where they can choose up to a specific amount of patterns, colors, shapes, etc. For them to build a custom hanging banner.
(DM level would have these and the exclusive golden style hanging banner to match the one we already have)
