I came up with the idea for these decades ago! Back then I didn’t even own a computer to design on. All these years later I remembered the idea and have now created them. The prototype deck of cards is sitting in front of me at home. Plan is to have a final product available to ship by this November on Etsy.com and/or its own web site. What are they? Flash cards of sins based on religious and non-religious sources. Already submitted to the U.S. Copyright Office. Update August 29, 2021: Major updates to SYNNCards.com and created a page for Facebook.
