7x9 Uncut - Off White, Mat Boards (Pack of 50)

that is now I need to cut out that inter or that inner rectangle for your mat or your frame just like a picture frame so you need this to go away this is a map cutting guide and this is a map cutting blade we're going to first use the guide and we make sure that this part is set at two inches you can unscrew this and move it up or down to set it but you can already see that it's set at two notice it says set scale with arrows this is the two inches that means from here to here is two inches we're going to take your railroad board you're going to slide it under this guide up against this piece and you're just going to take your pencil and put a pencil line and then you're going to rotate it and you're going to do that for all four sides and what that does is it automatically marks your four sides at two inches each so you don't have to do any extra measuring and then you can double check
