It may be a bit bigger card but it really is simple!
The base card is 9.25” x 8” white card stock folded in half.
(This will fit a legal size envelope)
Part way up I stamped the snowmen from Lawn Fawn “Simply Celebrate Winter” using Memento tuxedo black ink and colored them with Copic markers.
Next I stamped the sentiment from the same set with Versafine onyx black ink.
Now I cut, with scissors, along the bottom of the snowmen.
To finish I applied red polka dot card stock inside the front flap.
