An older friend of mine has decided that she doesn't want to sew any more, so she offloaded 5 boxes of stuff to me. I must confess, I passed a lot of that on, but there were a few treasures. Have a look at these buttons. They are like press studs, so that they can be removed for washing. I haven't seen anything like them before, but then, I am not a button collector or even an earnest retro / vintage shopper. There were 4 green buttons and 4 pearl buttons. I have no plans for them at present, but I am sure the right project will come along one day. Maybe a sweet, little clutch?
There was also this sheet of buttons. I read an article in Threads last year about buttons, but I can't tell if these are ordinary or special buttons.
