Solway Crafts and Miniatures will be releasing a series of printed flags on cotton material.
From their website:
We are now doing our 25/28mm. flags printed on cotton material. The VBCW range will be the first out. 30 sheets (plus a few add ons for the Empire conflicts) the first 16 will be factions,such as the League, Royalists, Left Wing etc, the rest will be Regions, eg the North East, Devon and Somerset,-each of these will have a mix of factions from that area. Aircraft recognition flags for vehicles are also underway and we hope to have the bulk of the revised range on sale at Triples. The Cotton flag sheets will be retailing at £6 per sheet
The 17th/18th Century range are also being redone and will be out shortly on linen.
