Sorry if I've missed it but what do I have to do to get the e-book or just some designs?

I tried that. I even offered sexual favours but it didn't help.

You offered to go to Boots for him?

The e-book is available on Lulu.

Anyone managed to print an image that works at playing card size or business card size? I've got a good working image at A4, but anything smaller doesn't work. What am I doing wrong?

I've not got the book, so this is just a guess. These images will lose their effectiveness if you scale them, so in order to create an image of a particular size, you need to start with that particular size in mind; i.e. you need to work at the right dpi for the size of printed image you need.

Grue is right, as you scale the image down, you're going to loose the fine details which makes the whole idea work. Start off with the smaller size in mind when you create the image but it's also worth remembering that these things are always going to work far better when they're printed at a bigger size.

Thank you Grue and thank you M'lady.

Reading though these forum entries, there are lots of great ideas about printing on Tshirts, business cards etc but has anyone done these things? I have produced good A4 images on photo paper or high quality non-absorbent paper.

I not sure it would work on fabric or on playing card / business card size stock. Hopefully some of you good people can prove me wrong?

When I was at college we did some of these on t-shirts which worked ok, I think you'll need to make sure the print quality is good though, I doubt those print them yourself, iron on transfers would be much good. I doubt that business cards would work though, I'd guess that you wouldn't really want to go down to anything smaller that A5 otherwise you'll start loosing the effect.

Just done some good A6 versions on high quality glossy photocards (for epson photomate printer).

I've got this idea of using small cards (ideally business cards) with the trick/treat images and a caption along the lines of: 'look closely to get your 'treat'' (then my web address) followed by the phrase 'the only 'trick' is to book me early to avid disappointment. I need to tweak the wording.

I can't get it to work on small images (e.g. business card size). I'm using the trick/treat one at 6" across to get a good effect.

The thing to remember is that a small image and a large image that is far away are conceptually the same thing to your eyes.
