The Cost

Cost is easy. 

Plain set with not paint = $100

Set with basic paint job = $150

Single Boarder

Stripes

Triangle

Opposites Triangle

Set with a logo = $200

I hand paint all of these.  No sticker business with my boards.

Bags are not included, but I do encourage you get bags from Amazon at a place called "Donkey Sports Cornhole Bags."  Great product and cost is $25 with shipping which is pretty typical.
