Most efficient method of tying roe bags?

[MikeH]

I have adapted my presentation since I am now sliding the eggs down the line from the pier head on a float trace and not casting them at all.

   

I use a food "glue" to stick them together to create a cluster or string of eggs. Obviously I am using fake eggs, (the scented ones) The string of eggs is flexible enough to bend a bit in the water motion. I have been experimenting with adding some float beads to the cluster to restore neutral boyancy once the hook is added.

One drawback is that this presentation attracts Carp and other fish too.

EDIT: not a very good pic, but there are actually two strings in that pic, not one big one....
