A most worthy cause is the Profanity Embroidery Group, formed by Annie Taylor and Wendy Robinson in 2014, based in Whitstable (see e.g. here). Admirable as were the early suffragettes, they may not have been quite ready for this (cf. the embroidered handkerchief).
As Annie Taylor reflects in this interview,
No skills are necessary: we’ve had people join who are excellent at swearing but complete novices at stitching, who are now producing amazing work, and then fortunately (otherwise our Quilt of Profanity would have been a nightmare) we’ve had people join with brilliant stitching abilities, but lacking a profane vocabulary. I’m glad to say they are also coming along fine and their use of swearing has improved immensely. One of my favourite reasons for someone joining was that they wanted to do something that was in no way “self improving”. […]
Some of our work is more subtle than others, but there is something rather glorious in beautifully embroidering the word Cunt. It is an old old word, but is seen as vicious and derogatory, the worst of the worst, but if you can happily use it, and stitch it, the word has lost its power to hurt you.
