I wish that putting the beads on backward was the problem. Nope, I put them on so that the small hole is up against the eye.

The problem I guess is simply that the holes are too large, especially the front hole. The 5/32 would slip right off the hook. The 1/8 will hang up on the bend of the eye, but covers much of the eye.

I went out and picked up a different brand of bead and the 1/8 stops at the eye. They didn't have any 5/32 beads so don't know if that brand will fit the #10 or not. But judging by the way the 1/8 fits I would suspect that the 5/32 will have too large a hole.

I guess the moral of the story is that even the suggested size charts have to be taken with a grain of salt and one has to go by trial and error.
