I make a large number of 4 1/4" x 5 1/2" cards. I thought this would be a quick & easy way to make accurate scores for folding the cards. NOT! When I score it, and fold it, the one side of the card is slightly larger than the other side. This is very frustrating, as the cards don't look professional then.
I love the enveloper board though. It makes making envelopes quick & easy.
Since they come as a set, I'll keep them for the enveloper board. Wish they still sold these separately.
