First step is to cut out diamonds... Use the diamond templete and I make it the full size of the templete...
Material need is---one very light
one as a medium
one dark
Easy hint... I cut 4 inch strips.. I place the diamond on stip.. Cut the first part of the "tail" off it so my diamond lines up... I move the diamond down the the strip and use my rotary as I go.. I am sure someone here may have an even better idea but that is they way I do it..
