Papercutting and silhouette-making has always been fascinating to me. Here are some Etsy sellers who do it extremely well.
Heart Garland by Sanfran 67
Perfect as a Valentine's gift (if you're up for spending $65 on a Valentine's gift!) The rest of Sanfran 67's store is jaw-dropping as well.
Large Art Card - London Eye by Nickolya
Nickolya does cut-outs of many major world cities' skylines - check out the shop for more!
White Peony in Black background by Molley Jey
A simple framed silhouette - this would be beautiful over your desk.
Bee Miniature Paper Sculpture by Elsita
Elsita's bee sculptures are basically the eighth wonder of the world, I think.
