Paper Selection
Because of the double layer on this see through snowflake card, you can use any paper for this card. Experiment with patterns maybe. The snowflakes need to be made from 2 sided paper, but a white backed paper is still two sided and white is a fine color for paper snowflakes. (See fun fact below)
The clear layer (grey piece in file) is made with acetate. If you don’t have any, try cutting an old mat cover sheet or a report cover. They both make excellent substitutes for acetate sheets. So do plastic packages that things are sold in, like dies. I use a lot of those.
