Yes, that's a shaker! I had a transformational experience watching Kristina make a (very similar to this, actually, although much more watercoloured) shaker card earlier this week and her method is SO. EASY. Double up the foam tape, cut it in half lengthwise and remove the backing paper and it will curve around your opening. And there's enough depth that the sequins don't get stuck in one place, which has always been an issue for me.
This card is for this week's Inspired by All the Little Things:
I felt like the sequins in the shaker would capture some of the sparkle from the glass in the flash bulb area.
