My brother and his family visited me often, and on one such occasion, my sister-in-law brought everything with her for us to make cards. My first comment to her was - "I'm not creative". I know, everyone has said that before!
I spent the next 2 hours making my very first cards and I was surprised at how fun and easy it was. We even toasted to my "creative genius" afterwards with a little champagne :)
The only thing I have to say to you is - If I can do it, so can you!
