Do the last first
(Las Cruces, NM)
I am still a novice card maker and it seems like the times I am likely to mess up my cards happen in the very last stages of making the card.
Now I try to complete as much of the final layer as I can early in the process...and then build the matting layers after that.
It's not always possible to do this, but it's certainly easier (and not as heartbreaking) to start over when I haven't invested so much time, materials and effort.
