I really liked the simplicity of using the spacer cordage in that I could create different combination of signal flags very quickly as it was all based on the same spacing -- be they signal flag or space between words, or even to fill in on either end of the signal message to hang it easily. My husband loved seeing his Amateur radio call sign displayed in signal flags for Fathers Day.
I cannot wait till we can challenge some of the youngsters to decipher other combinations as they visit us at the lake. Perhaps over time we can add to our collection and have at least one of each letter and number. This shall be fun!
