I've taken all your tips on board, and made a new version:
I like this one much better! :o)
I used Chocolate Chip card base, instead of the Groovy Guava, and stamped on Whisper White, instead of Very Vanilla. I substituted Groovy Guava stitched ribbon, and used a rub-on for the sentiment. I also switched the sentiment to the other side,so it would be more balanced. What a difference those few changes make!
I actually like Groovy Guava, but as some of you said, it has to be paired with the right colours, and in the right proportions. Some of you suggested switching to Chocolate Chip ribbon on the first card I made. I did originally have Chocolate Chip ribbon on there, but it just didn't look right with the words stamped in Chocolate Chip too.
OK, so let me know what you think of this one!
