Ducky, you are Elle will be the death of me - I haven't laughed so much for ages, and with a face ache infection, it HURTS!
Sorry you thought no. 15 was a stinker - but you must have hearts down pat now, having done 16 of them, so it was good practice. The next block that has some won't be so hard. I'm still wondering why you picked no. 15 anyway, are you just picking them at random or what?
