Shirley said it didn't have to be 100% SU but at least 80%. Mine is 100%. I didn't have any halloween stamps that were SU (all I have is frilly stamps from SU) It also needed to be 3-d so I made my major LO with my digital software from SU and cut out a few extra images to pop up with pop dots. I used a tag for my tombstones and then digitally inked them so they would look old! COOL HUH!
I also digitally inked my clouds and moon. There's a tutorial on Stampin' Up's web page.
I also had to add bling!
My cutting out images added to my LO's scary-ness! LOL!
(Can't cut very good!)
