I love this little invention. I can make any size envelope with this board. I like making greeting cards but the cards always had to be made to fit the envelope size. Now I can make any size card I want and can also make an envelope to fit that card exactly. I always used to be stuck buying envelopes in the colors they had in the stores. Now I can take my scrapbook paper and make a pretty little envelope with it in less than 2 minutes. I love this envelope punch board so much!!!!
