Personally, I can't think of any reason why you wouldn't ♥
Here is one that matches my flower notecards. These come in packs of 50. With different color flowers, because I wouldn't want you to not have choices. And because...sometimes it's a yellow day and sometimes it's a pink one.
I have several others that I will be adding to by etsy site soon. Just gotta get around to uploading all of them :)
