Happy Mail *card kit only*
I struggled with the octagon shapes a bit at first. They looked too angular for my taste so I played around with them and decided to stamp a pattern with the back of the stamp and one of the pointed ends up, so the whitespace formed a nice star image. The neon splatter was made with a Hero Arts paint dauber from the shop by "punching" it onto the cardstock. After it tried, I stamped and heat embossed the sentiment on top.
