I removed the mask and had a lovely "beach circle".
The card base is Soft Sky, and there's a layer of Crumb Cake between the bottom and the top card front.
And then those shells! They are two-step stamps; the sand dollar was stamped in Sahara Sand and Crumb Cake; the shell in Powder Pink and Blushing Bride, and the long shell (is that a conch shell?) was Soft Suede and Chocolate Chip. Each shell was fussy-cut with my Paper Snips, then adhered with Dimensionals.
