Painted on a canvas panel measuring 152mm x 102mm, slightly larger than a postcard. The thickness is about 4mm. I used glitter and medium. The small, colorful particles are glitter. It looks a bit more sparkly in person. The actual colors are closer to the second image, which was taken with a flash. The glitter effect is closer to the first image. Mini easel not included. #AcrylicPainting #Jellyfish #Sea
