|I made a button down blouse and couldn't find buttons of the appropriate size for it. The ones that were the correct colour were just too small.
Also, fitted blouses often gap immodestly when you're not 'posing just so'..... sigh
Fixed two problems at once by buying the smaller buttons. The blouse called for 5 buttons, so I bought 10 and spaced them in twos.
I measured where the buttons should go, and placed one small button half an inch or so above that space, and another one half an inch or so below the regular button placement.
I put it on, pinned it to see how it 'stood' and it was better than using regular buttons.
