Treetacle testing proceeded today. 

Tree failures and one success.

The first two twigs failed by being too leaky so we had a bad case of limp stick syndrome. 

The third one survived long enough to pull itself apart through the fabric at the seam.

The fourth stick got sealed by heat seaming.

I improvised to see if this would work by dragging the tip of a hot melt glue gun through the material, and then I sewed through that. It worked.

Cleaned up and I'm coming back tomorrow.
