I used the colors from Stampin' Royalty's challenge and the sketch from Nacho Average Challenges - both challenges I haven't played along with for a while.
The Silhouette file was one I bought from the online library and I think it is called Random Dots. I just cut it out of some cardstock, although I do note that Silhouette have just introduced stencil material, which is pretty cool.
I sponged over the stencil in Tangerine Tango, Pool Party and Pear Pizzazz. I then stamped the sentiment from Avery Elle in Memento Tuxedo Black ink. I wasn't going to put any sequins on there, but I sort of splodged the 'y' in 'day' so I had to try and cover it up LOL.
I layered that onto Sahara Sand then onto the card base. And continuing with my resolution of finishing the insides of my cards when I make them, I did some simple stencilling on the inside as well.
Thanks for looking.
