I am challenging you to go over the edge! I want to see something hanging off the edge of the card. You might want to consider adjusting the size of the front of your card so that it still fits in a regular envelope. For example, if your shape goes over the edge by 1/4", make your card front only 4" wide instead of the standard 4 1/4". If your shape goes over by 1/2", make your card front 3 3/4", etc. I hope you have fun with this - I'm looking forward to seeing how you handle this challenge!
I recently picked up some flowers and flower dies by Essentials by Ellen, and I thought this sketch was a perfect place to highlight them. The flowers have a matching stamp set, and I started out using the stamps with my brand new ombre stamp pads, but quickly realized that the stamp pads are simply not in colors that I liked (but it was a great effect!) I ended up just using the dies and finding paper with an ombre effect so that there is a slight color variation across the flowers.
