My friend Amy suggested that I paint one of the milk lids gold to make it pop and be more festive, but... paint sounded like work. And drying time. So instead I cut a four leaf clover from some brushed gold vinyl (using my Silhouette... I'm old-school SD not new Cameo :), and stuck it on one of the milk lids.
As a bonus, the vinyl will peel right off once I decide to take the art down and let my kids have their milk lids back to play with. But... let's be honest... those kids are never getting these green milk lids back. And the other colors are in danger, too, because momma is loving on how easy and cheap milk lid specimen art is! Next time, though, I think I will leave some space between the milk lids to give it more of a specimen feel. And there will be a next time. :)
Happy St. Patrick's Day!
