Specifically, let's see 3 images/words/items on your card that remind you of summer and all the fun that comes with it.
This challenge took me a while to figure out as I do not have the stamps nor the paper for summer fun. So I made some creative accommodations. Song that comes to mind is the Itsy Bitsy Teeny Weeny Yellow Polka Dot Bikini. Instead of cutting out a yellow polka dot bikini, I opted for polka dotted sun, clouds and the sea with a simple cut out of an island in the sun with swaying palm trees. The pattern of dots paper is Chiyogami paper from Daiso. The island is just cut freehand from green cardstock. The tree trunks too cut freehand from brown cardstock. The swaying fronts are Hero Arts stamp which I used in the earlier money tree bonsai card. So my 3+ images/words/items are the sun, the island with swaying palms, and the blue sky and sea. Have a wonderful summer holiday. It is summer all year long in Malaysia.
