My first kit will be in Scrap Bird shortly!

Just wanted to give you a peek at my new mini-kit, it should be up in the store shortly!Don't forget to grab the Designer Survivor freebies, the download links will expire soon!

I decided I'm going to have a contest, the first person to comment with the correct answer wins this kit! If no one gets the right answer by noon central time on Wednesday I will use Random.org to draw a winner!
The question is: What did I use to made the dot pattern on the pink paper?
