I recently really latched on to glue basting - and I love it. I tried mixing with water and spraying on and that did work but the quilt got stiff stiff stiff - almost like a board. I will never do that again
I buy the glue by the gallon on Amazon and then I put in the 7 or 8 oz bottles. I found that if I mix about 20% water with the glue it squeezes out the bottle much easier
I like the idea of storing upside down I will be trying that
