Background Help!!

Ii have spent ages trying to get this darned background to work and it wont!! When I preview the changes, it's fine but it's shrunk when I check back later and I'm getting VERY ANGRY GRRRRR.

Anyway, if anyone can help with (with the background, not my sanity) I would be eternally grateful :-)

Going to chill out now and make a couple of cards to calm me down ......

Will post the results later in the day.

Ooh, nearly forgot HAPPY NEW YEAR EVERBODY XXXXXX
