Among the many experiments that I've been conducting in materials for basing, I accidentally stumbled upon a possible idea for making blood drips from weapons. This would expand upon the technique that I already used for making blood, which involved transparent red paints and Secret Weapon Realistic water.
The additional ingredient would be Liquitex gel medium, which I had gotten to use as a clear water splash material. Initial tests proved this material to be even more robust than the Vallejo water effects medium, which had a tendency to collapse or shrink.
As a result, several layers needed to be painted to get a desired wave or splash effect. I was quite surprised at how well the Liquitex gel held its shape!
While flames and other non water techniques are things I have already worked with, the use of blood spatter and 'trails' of cast off blood had not been tried until now.
I ended up using a strand of foliage material, which was very thin, but very strong and rigid. It attached it to the weapon with a gob of the gel (with paint mixed in for color). Once that was secure, I started placing additional blobs of water effects (also mixed with paint), and a bit of the gel.
Letting gravity do its work, I was able to create the impression of the blood dripping down! Success!!

This image shows the materials in question. The Liquitex gel medium provided most of the 'body' of the blood, while the Secret Weapon Realistic Water made everything more shiny and transparent.
