Paper Selection
Since you see both sides of the paper either two sided or solid colored paper is needed for the base card. Everything else can be whatever color you want as long as you can see the writing.
I went with traditional Christmas colors since this is a thank you for Christmas presents. It can be easily adapted for any occasion.
Cutting the Twisted Christmas Thank You Card
I went with a white pen because it showed up well and seemed appropriate for the snowflakes.
This card is very easy to cut.
