@elfi *hoards the pieces not yet inserted*
@Maddyflen It's acrylic! First time I've ever seen one like that myself!
Similarly I may paint or spray over it with a medium or sealant to fill the seams
@elfi a puzzle of a dragon, with the missing pieces being in the hoard of the dragon in the art
@Maddyflen also the idea of a jigsaw puzzle with pieces missing as an art project sounds like fun
