My friends and I attended a class at Stamp This...Scrap That in Minoqua, WI and we created a similar card using a die cut filigree heart. I saw this Impression Obsession intricate die (DIE093-X) at this store and it was a must-have.
I have never worked with such a detailed die before but this was amazing. Many different ways to use this die for sure. I cut an A2 sized panel and die cut somewhat off the paper as shown. Behind the panel, mount decorative paper or create your own background. Then replace the die cut and adhere onto the negative space. This die had an outer area that it cut which I removed. Hard to explain but if you have, or purchase this die, you will see what I mean. I then embossed the panel with a snowflake embossing folder and mounted onto light gray card stock. Added a snowflake brad to complete the card.
