Harry.

You say you are not completely happy with your dartboard?
And you ask for improvements?

Well, from what I have seen, just on 'talkgraphics', there will be many who can suggest much.

One thing I can tell you Harry, 'everything is relative'.

You are looking for improvements, whilst I would be grateful if you posted DETAILED INSTRUCTIONS on how you made this Dartboard !!!

Here is the relativity bit.
"Relatively speaking, you are a master compared to me."
