Dimly remembered tranny-related shows

I've forgotten more telly shows from my youth than I remember, but the ones that had a "tranny element" tend to stick in the mind, long after the name of the show, or even the plot, has faded.

For some reason a bizarre British drama (or possibly comedy) I remember seeing as a teenager popped into my head yesterday, and I'd really like to find out what it was called. It's almost impossible to Google about, so perhaps it will ring some bells with you.

From what I recall, it was partly about a fictional soap opera set in a wool shop run by a group of ladies of the type who run wool shops. Think Acorn Antiques, but with balls of wool instead of antiques. But this was just the "show within the show", the actual drama was about a bunch of furtive middle-aged trannies who "reenacted" the show in a mock-up of the wool-shop set made in one of the tranny's houses. In the "real" shop had a wall of cubby-holes filled with multi-coloured balls of wool, the fake one was painted to the same effect.

The drama (or comedy... it may have been a comedy) revolved around these strange trannies gaining a "kick" from role-playing the female characters in the soap, and I seem to remember one plot involving jealousy over who got to play which character.

So there you have it... actual details may have been different from how I recall it, but it did exist and it's not just a figment of my fevered imaginings. Any ideas?
