One can never have enough thank you cards around.
1. The envelope is 9" x 4 4/3".
2. The inside card is 5 1/2" x 4".
Depending on what glue you use to close the envelop.
You might need to trim a 1/4" off for a better fit.
3. Arched the top of the inside card and
rounded the bottom corners.
4. Used graphics from the old pccrafter site by
Kimberly Montgomery "Peace and Kindness".
I could not find where her graphics are for sale any more.
