If one ever wants to add that little something to a card, prisma glitter is a great subtle effect that packs a gentle blingie punch. I'm not sure you can see it on the photo, but the cake slice (from PC Hugware) is outlined with a 2 Way Glue pen and then sprinkled with glitter. I keep the glitter in a resealable container so I can dump it directly back in the container.
The inside of this card has a fun pop up cake. I've made a tutorial in this post showing how to assemble the cake.
This cute little cake is made from a flameless tealight. I thought it was a fun addition to the go with the card.
