Here's some useful and easy tips for you. Have fun with your decoupaging.

1. Don't use thin images. More often than not they will tear.

2. Don't use papers that have images on both sides. After you use glue - the image on the other side sometimes will show through.

3. Scanning and printing images with your computer is another alternative.

4. Paper is too thick? A simple method to make it thinner is to split the paper in half. You can do this with your fingernail or even use a toothpick. Then just peel it apart. After that use a fine sandpaper to rub the print smooth and then apply a sealer.

5. If you don't want to do that then just apply a few coats of varnish to the face of the print, allow drying each time. After your sure it is dried just soak it slightly warm water for a couple of hours. Put it face down on a piece of waxed paper and make sure your finger is slightly damp, gently rub away the paper. Don't rub too hard or you are liable to rub right through your print. Sand and seal it.

6. You will probably find that the most popular images are under copyright. Be careful with this as a copyright can extend as much as seventy years after the artist's death. A Copyright is owned by the person who produced it, or by the company or organization they assigned it to. Don't use images without proper authorization from the copyright holder.

You may or may not get authorization to use the copyright. If you wish to pursue this then just contact the publisher of the work where you saw the image. Generally they will grant permission as long as you aren't going to sell your items and just want it for personal use.

7. Using images from magazines or gift-wrap should be Okay.

8. Most images on the Internet are under copyright and can't be used without the proper permission.

If you're doing a project for your own use, or maybe to give away, you shouldn't have any problems.
