Both are nice, but I personally like the first one best. On the second one, the letters & the heart seem to be garbled up with each other, so neither the heart nor the letters stand out.
The first one your eye knows what to look at; the second one your eye keeps moving around & doesn't land anywhere, thinking what am I supposed to focus on.
I thought I liked another poster's idea of leaving the letters off, and putting them on the label on the back.
But, on the other hand, the letters on the first one make me smile and think, "Aw...isn't that sweet!" Without the letters, I would think "Oh, that's a nice quilt, but it needs something else to make it pop."
It will be fun to see what you decide to do!
