Have you tried to put carefully small elastic under the beads? I am searching for those and will try if I find one (not pandora stoppers, ordinary tiny-tainy plastic bands). I read the tip in older thread. When I have 2-3 beads in each section, it us amost the same - they do move around but there is still enough space to peep and they are not all together.
Oh that's interesting, I've never heard of those, I have the stoppers you mentioned to use with clips. I do remember seeing some different plastic stoppers but you could see the plastic around the sides. I will have to do some research.
