I thought I would challenge you to do a card with geometric shapes on. I goggled the definition to be sure I knew what one was LOL !!.
Google states "a geometric shape is anything that when rotated still remains the original shape ie: circle, square, triangle, hexagon, pentagon, and octagon etc"
So Here is the card that I've come up with !!
A birthday card, consisting of octagons !!
Visit the MAWTT, and see the other DT entries.....or why not have a go yourself? Just for fun xx
