I normally press all my strips and then start cutting my pieces. I am going to start by cutting the very end of my strips with a 45 degree angle on them. Then I turn the strip and line it up with the length of point I want to make. In this case the first one would be 3". So I am actually making 3" diamonds at 45 degree angle.
Cutting end of strip with a 45 degree angle
Turned the strip and now lining up the 3" length and the 45 degree line to cut my diamond.
Continue cutting until you have 8 diamonds
