I never would have put these colors together, especially for a Valentine's Day card, but I think they work great as a pair!
The sketch I used is from Splitcoaststampers, sketch SC418. I haven't used a sketch from there and thought it worked well with the hearts. I am loving this stamp set, Hearts a Flutter. My dear friend Aimee got the bundle for me for Christmas and I have been using it a ton. The set also has adorable banners in it, which are very popular right now in the crafting world! You can find it in the new Spring Catalog if you are interested in it.
