AAAMA~ Christmas card and postcard

One of our swap-bot friends is taking care of her 101 year old mother.
She would love some Christmas cards or pretty postcards.

So, here's the swap:

When you sign up, I will send you the name and address of the elderly lady. You will send one piece of mail to her and one piece of mail to your partner.

It's your choice if you want to send the card or the postcard to your partner. The other piece of mail goes to the 101 year old lady. Because of her age, she would prefer bright colors and large print.

Have fun decorating the envelope or postcard to make this fit the description of "mail art".

Again:
Create or buy one postcard AND one christmas card.
One piece of mail goes to the elderly lady.
One piece of mail goes to your partner.
