This card layout is so basic you could use it for almost any occasion or season just by changing colors and the sentiment on the tag.
Just use a border punch that you like for the left edge piece.
Cut two pieces of patterned paper 5.25 x 4" and then cut that in half horizontally--this will give you two fronts.
Stamp a sentiment and manually cut out a punch shape.
Attach a few small flowers or any embellishment you like at the top of the tag.
The small flowers I used on this card are some found in the bridal section at Michael's. I colored them with Promarkers and added some red dots on a few.
This would make a great invitation if you just put "You're invited" on the tag, don't you think? And it took less than 30 minutes.
