I shan’t be washing my winter coats and putting them away at the moment - I think there’s potential for further cold snaps yet.
However, whilst it is nice, I have started some fettling, but I don’t tend to do a massive spring clean, but rather keep on with bits throughout the year. Having said that, what I will do as soon as it warms up a bit is wash all the curtains, as some are looking on the grubby side. They take ages to dry, so I need to wait for a warm, sunny day to do them.
