I was also asked to make a card for a 13th at the same time - here it is:
This one is A4 in size, the base made from some A3 card I have.
Papers, I think, are DCWV and are encapsulated glitter - although its not very clear here.
I ruffled some seam binding along the side and bottom, then cut the numbers with templates and edged with black stickles.
Mulberry paper flowers were added to the bottom corner with a maribou feather,
the same theme added to the bottom of the "3"
The letters were cut with my Cricut and shadowed with black.
I didn't want to use the glitter card in the machine so used plain pink and sprayed them with Crafters Companion pink glitter.
The dots were added with black stickles and some gems used on the numbers in hot pink.
A layered butterfly was added to finish.
Check out the Scrapology website, the challenge is open until the 15th September.
