The card for which I made this particular envelope measures 5x10", so yeah... it's BIG! I like to make collages, and when you're working with original vintage items, they are whatever size they are. Luckily, it's super-easy to construct a custom-sized envelope. I started with a piece of vintage wallpaper measuring about 11x16", but you could use any oversized sheet of giftwrap, kraft paper from a roll, or even an old map.
Neatly fold and crease one side so that it's slightly shorter than your card... this will be the pocket into which we slide the card. Next make another fold a couple of inches from the opposite end... this is just decorative, to give the top flap a nice clean edge. Finally, make a nice crisp fold just about in the center between the other two... and that's it!
I made a little cluster of Solid Color Paper Flowers. Since each packet has three different sizes of blossom, and a total of 40 flowers, I could afford to be a bit lavish and stack some of them, securing the centers of the larger blooms with 15mm Pearl Brads, and the smaller ones with 5mm Pearl Brads. At the edges of the arrangement I used some gorgeous creamy Pearl Swirl Bling. These are absolutely beautiful right out of the package, but in this case, the flourishes were not quiiiiiite the right shape, so again, I went with the "customized" option. I left the swirls attached to their clear backing sheet, but snipped the swirls apart and re-arranged them. Once I had exactly the right positioning, I peeled them off their backer and added them to the design. Et voila! One special collage card in a very fancy presentation envelope!
I hope you'll be inspired to think outside the box of standard sized envelopes and give your own handmade cards the couture coverings they deserve!
