I'm really into these blue/aqua and lime green buttons. Of course, a quick spin through the Yellow House Knits collection confirms that I'm really into those colors generally. But I think the color combination and he slightly irregular shape would really jazz up a sweater. I'm seeing them on a little boy's sweater, but I think they'd also be darling on a girl's sweater. They would be fantastic on a sweater knit in these same colors (maybe a cardigan with blue and green stripes?) or on something in a contrasting color (maybe a red and orange?). Let me know if you have a different idea! I'd love to create something with you.
