I used the recipe at:
I used a bath size bar of Ivory soap and followed the rest of the directions except for waiting for it to set up before pouring into empty detergent bottles.
I poured it into the bottles right after finishing mixing it in the bucket.
I did not have enough empty detergent bottles as someone helpfully disposed of the empties.
The detergent gelled fine in the bottles. I did not fill them all the way full so there was room to slosh it around and mix it up.
My Ivory soap was a bar that I had had for a while and had dried out some. That meant that when I grated it I got a fine powder instead of the curly slivers. If I do try the recipe for the dry detergent I will use an older bar of Ivory. I age the bars for shower use as they last longer than the new wet bars.
It will sure be nice if it really works as well as some people say. I have seen mixed reveiws.
I did not take any pictures as it is not really very photogenic and there are plenty of pictures at the recipe site.
