help me choose buttons

Hello! Today I’m putting the finishing touches to a new cardigan which (all being well) I’ll be able to show you on Friday. I have spent the past hour or so poking around the button box . . . with some success, and a wee bit of frustration. I fear my button-vision may no longer be objective, and so I need your opinion. And although I find the set above, with their hands permanently set at 12.15, extremely pleasing, sadly there are only 6 of them, while this cardigan has 9 button holes, so they cannot be used . . .

Again, there’s only 6 in this old formica-like set, which is definitely something of a shame. . . .

I like these blue buttons, but fear they might limit my wearing options. Would these buttons mean my cardigan always had to be paired with something blue?

These wood buttons are . . . ok, but in comparison to the clocks, they just don’t make me that enthusiastic.

and although I rather enjoy the marmalade transparency of these buttons I feel the yellows of yarn and buttons may be competing.

These tiny yellow ones match the fabric of the buttonband quite well . . .

. . . but I think overall that these glass ones are my favourite . . . that said, my opinion may well be skewed by the fact that it took me about half an hour’s poking around the button mountain to dig out 9, and they now feel rather precious. Does the fact that I know that these are the only 9 small, glass buttons of this type in my possession make me want to use them a little bit more?

What do you think? Which buttons should I use? Glass buttons, tiny yellow buttons, wood buttons, or marmalade-yellow buttons?
