I just used a spring clamp to hold the string to the upper edge of the cabinet, as for the dishes, I had it cleaned up before, and during the process, wife and two kids in the house, they grew back! The hole was difficult! At first I just poked a hole in the bottom with a drill bit, that was way too big. Got another bottle and used a pin this time, found out you also must have a hole in the top also. Had to adjust it a few times with tape but finally got it to drip the way I wanted, I thought, as the water level in the bottle dropped, the drip got slower and that's when I started to get really good shots. It took a little time, but it was hot out and the lawn needed mowing, I was very happy to stay inside and play with my camera.
