Thanks for these logos! I love the font and how you incorporated the tag line underneath. My favorite one of these is #4 because the hot pink color is bright. I also like the fact that I can use the heart with the K in it as an iconic logo. I'm wondering if there's a way to do the heart icon so that it has a "K" and a "D" for Kate's Dates? or if there's a way to arrange the letters in the heart so that there's some kind of shape or letter that's readable whether you're looking at the white space or the pink space? Do you know what I mean? I think it would be cool if there were multiple ways of looking at the heart shaped logo...
I created some concepts with a K and D in the heart. There isn't a way to arrange the letters in the heart as you ask me because this is an handwritten font and it is not symmetrical like a serif-sans serif . Now I think that the heart looks very good and unique and it can be used separately as your symbol without the text. Also I tried different backgrounds and as you can see the logo looks good on every color. If you have in mind other changes please tell me them and I will provide.
