So yesterday I decided to celebrate this occasion with co-workers. Created 60 kits of these two cards and during lunch, we invited all who wished to participate to make a card of their choice.
Card #1 uses Studio G stamps, Sizzix tag, MemoryBox Co. Cloud Die, embossed with SU Square Lattice and 2 scraps of paper.
There was another 3 x 3 card but I didn't take a picture.
I hope you shared World Cardmaking Day with others!!
