I will be making several gate fold cards, including an inside pocket to hold checks and/or certificates.  We have made special donations to international relief efforts of Samaritan's Purse - to honor our children and grandkids, so we include that certificate for them.  I used "nameless" dies for the sentiment and the nativity.
More than one fold:  Scor-Pal
