I have a small collection of vintage buttons and here are just 3 of them. most are from the 1930s or 1940s.I particularly like the ones made of mother of pearl a central band of which is on the 1st one. This is the back of a large square mother of pearl one. I have 3 of these. The 1st one with a similar smaller button. They are quite shiny so you can see the reflection of my conservatory windows in the 1st one.I have in the past used some of my collection on dresses I have made or cardigans I have knitted.
