I'm just making my second one of these and they are so cute :) Very fiddly for me as I've only been crocheting a little over a week but my first one looks very acceptable.
I am making one for DS2 and DDs teachers at school (they are getting big presents from class collections - these are just for fun).
I have also made one solitary heart. Only because I got seduced away by apple key rings. I plan on making lots of these and hanging them from twigs or something (somewhere else on the blog she did this and it looked lovely)
