Vintage buses back on the streets
On Saturday, you can hop aboard vintage buses for free. The London Bus Museum holds another of its heritage days, putting buses from the 1930s-70s out on the roads for us to enjoy.
The vintage vehicles run on a short stretch of the 106 route, between Finsbury Park and Ash Grove Bus Station on Mare Street, via Stoke Newington, Clapton and Hackney Central. No ticket is required, though note that due to the age of the vehicles, wheelchairs and buses can't be accommodated.

Balham's shrine to sewing machines
The monthly opening of Balham's Sewing Machine Museum on Saturday afternoon is a chance to view a private collection of dozens of the machines, including one made by Pollack & Schmidt from 1865, which was presented to Queen Victoria's firstborn daughter, Vicky.
Entry is free but charity donations (The Royal National Lifeboat Institution or Leukaemia Research) are very welcome.

Seasonal shenanigans in south London
