It's pretty simple, just make a plug you are comfortable making and have experience with. No stress, just a challenge to do the best job you can do. I think that is what bigfish had in mind.
The way I figured it was, that whoever gets me to build their plug of choice, they will ask for something I am able to do like a pikie,needle,pencil,spook or something like that.
Can I go in and get slip to make 2 plugs..
FORE!
It's usually darkest just before it turns Black..
