Valentine's Day is a favorite of mine and I've created Mail Art Valentines for family and friends for many years (see 3rd photo) ....and they still have them.
Fabric Valentines can go though the mail without an envelope using a regular stamp and extra handling stamp. They can later be framed....or just played with as my grand daughters like to do.
"Delight yourself in the LORD and He will give you the desires of your HEART"
Psalm 37:4 "is the featured verse on this 4" X 6" small Quilted Art Quilt that encourages the recipient with Truth.
This one and more are in my Etsy Shop.
