re: Trout Nets

WOW, I saw these and I just was in awe. Both myself and son love fishing. So I’m going to ask how difficult was it? How would you rate novice, middle of the road or experienced? Did you have plans if so where from? Where did you get the nets from? And what finish did you use?
I ask you these questions because I truly want to make one for myself but especially one for my sons 18th birthday. I know this is something that he could use with the pride of his father made it for him.
