As inspiration for Halloween I have chosen Bat Boy to work with. I must admit I am not big on celebrating Halloween - back when my kids were growing up, it was not a big thing in Australia, but I always have some lollies on hand if I get a knock on the door, but that didn't even happen last year.
I chose to make a treat bag and picked up this bag from the cheap shop ages ago and remembered I had just the right size for the image I had printed. For the background I just used some Halloween papers I had on my computer. I hope you can see my creation OK, for some reason I had terrible trouble trying to save the image with the watermark through Picmonkey and had to try GIMP, which I know less of than Picmonkey.
