If you are specifically looking for Unicorn, the only one I have ever seen on this site is under alphabets in the tags section. It is not a full alphabet, but the U is pictured with a Unicorn. There were 2 valentines, other than the one design under Heart. I don't know where it has gone. The witch is under Halloween. The only other design that I have saved under U-Z is "vegetables". So other than the missing Valentines, it appears to be scant on that end of the alphabet ;)
Thanks, your answer was very helpful jrob,the unicorn's cute. A flower is on it's way to you as a thank you.
It would depend on what tags were attached to the design. "Witch" could instead have the tag of "Halloween", "Unicorn" could have the tag of "Fantasy", and "Valentine" could have the tag of "Heart" or "Love". If she didn't think to stick on a tag that falls in that end of the alphabet range, then they just won't be there. Did that make sense?
I forgot to say that the tags don't necessarily correspond to the actual name of what the design depicts. It is a search tool, but it is only as good as both your and the "tagger's" imagination. =]
Thanks for that cutiepie, I didn't think of that one! I've sent you a flower for your help.
