The inside 'seat' has been brushed, cleaned & "freshened" using Fabreze spray. The outer panels have all been washed & although they all shrank (I'm hoping won't make too much of a difference in its renewal as when originally made, shrinkage was allowed for).
By the way, the inner 'seat' (above) was made using an authentic 'Humpty' pattern & was filled with an extensive range of cut-up odd fabric scraps, tights, pop socks and anything else I came across to use. Cut into very small 'packing' pieces, the "innerds" resulted in a very heavy seating and perfect for its use - a highly recommended way of using old textiles & better than just throwing them away!
Here's the outer 'bag', washed & ready for repair of the brass rings (hopefully I'll be able to find the spares!)
