I will add to Beckie’s suggestion of coloring one side of sheet
solder to identify the type. Color BOTH sides. Think about how
time-consuming it would be to separate those little solder chips
should somehow they became mixed up, and you have to turn over half
of the little pieces to determine the color…
Color both sides and you might be SO glad you did! Yup. Been there,
done that. Now I color both sides!

ground. Lovely, but we really need more.
