To start off, I found an envelope where I liked the size and shape then carefully took it apart and used that as my template.
Cut out a piece of fabric & single sided interfacing slightly larger than than the envelope. Iron them together. Next, Pin fabric/interfacing to envelope template & cut out. Iron the fabric again where the envelope will fold. Lastly, use fabric or hot glue to adhere the seams together. Don't glue it shut though. :)
For the flower embellishing above, iron fabric to a thick interfacing (about the thickness of felt) then die cut the flower shapes (I used the Big Shot). Add a cute jewel brad for the center.
For the inside of the card, cut a piece of thick interfacing & fabric that would fit inside the envelope then iron together. Last, I added a cute doily from my Girls Loft kit and another strip of fabric sewed on top to hold the gift card in place.
To make these flowers, first, die cut or hand cut about 8 layers. (My trusty Big Shot came in handy again.)
Cut about a 3/4" circle of felt. (That's what you'll use as the base of the flower.)
Next, fold flower in half then fold in half again. Last, use hot glue and adhere the folded point to the felt. Continue adding folded flowers until you are happy with the blossom. I used about 8 for this flower but have also used 4 and added a button center that was really cute too. It just depends on what you like.
For the heart below cut a square of fabric and thick interfacing then iron them together. Next, cut out your heart. Then sew along the envelope's edge. Last, glue the heart to the top flap of the envelope.
For this one I hot glued my favorite fabric letter stickers to the envelope for a simple touch.
Enjoy, and use them for sweet notes & cozy messages.
