I have a number of pictures which I'd like to hang on the wall (without frames). I don't want to ruin the pictures using pins, and tape does not work because they keep falling.

Do you have any suggestions on how I can hang them without damaging them?

Also, any creative decorative tips are welcome

Thanks.

get a big clip (you could also use the wooden ones which are normally used for hanging clothes), hammer a nail into it and then hammer it into the wall. Clip your masterpiece on and woala!

...you could also decorate the clip and if you don't want it to leave a wrinkly imprint on the picture, get a bit of cloth, make it into a small cushion and stick it on the inside of the clip

hope this helps
