You should use metal tweezers for placing the dubbing either in the hanging
loop, or on the dubbing block. This eliminates a lot of static problems.
Doing it with your fingers can be a real pain.

Lastly, you can use a bulldog clip here to aid you. Clear plastic ones
which close accurately are the best. Although metal ones may be better if
you have problems with static.

Place the bulldog clip over the hair on the pelt which you wish to use. The
hair inside the bulldog clip should be slightly shorter than the length you
require. Now take your scissors, and cut along the hair, leaving at least a
millimetre or so sticking out of the clip.

Form your dubbing loop. Open it slightly, offer the clip up to the loop, and
allow the loop to close over the hair butts which are sticking out of the
clip. Pull the loop taut, remove the clip, and spin the loop tight.

This is easy to do, and results in dubbing with very short roots on one side
of the loop. This is easier to tie in without "folding" etc.
