Or try a beanbag... it doesnt come any easier... Dried beens, pees, corn of whatever you have... put 'm in a bag... and there you go..

Put the camera on top of it.. put your camera on the timer and take your pictures.. dont know if you have any control over the aperture but you could make it smaller (higher number) for sharper images (it increases the depth of field. it will increas the exposure time but that shouldnt be a problem with the beanbag.

Good luck.
