Slippers recommended

Since I don't have enough work at present to keep my occupied throughout the working day, I have been doing an awful lot of cross-stitching. 

I really don't know how it happens, but I lay down the needle and when I next look, it's gone. Sometimes, I find it lying on the floor, but it doesn't take long before it disappears again.

So far, I have lost three of them without trace. 

Hence my recommendation for wearing slippers around my flat. Given the number of needles I've lost here over the years, it must be rather like a pincushion, simply bristling with needles.
