I found this really nifty project on one of my favorite blogs, How About Orange. Using some plain white envelopes and pretty washi tape, you can create little bags perfect for party favors or tiny gifts. Go ahead a create a few today just for fun!
You’ll need an envelope, decorative tape, and scissors. I used 4 3/8″ x 5 3/4″ envelopes, but any size will work.
Seal the envelope and trim off one of the short sides to make an opening.
Wrap tape around both sides of the envelope. No need to cover the last inch, since it will form the bottom of the bag.
Fold about one inch of each side of the bag toward the middle; then fold the bottom upwards, creasing your folds well. You can vary the width of these flaps depending on the proportion of the bag you want. Flip the bag over and reverse the folds along the same lines for easier shaping in the next step.
Put one hand inside the bag, and with the other, push the bottom fold down. This will leave the bottom corners of the bag standing up. Press each corner into a triangle.
Fold both triangles down and secure them with more tape, covering the bottom of the bag.
Fill with whatever goodies your heart desires, fold over the top and seal with a small piece of tape. Enjoy your new thrifty creation!
