This is what we're making today: A sturdy kraft cardstock envelope with a string closure. The finished size is about 6.75 inches by 3.5 inches.
Each envelope kit comes with the base (pre-folded), two sturdy circular tags, two brads, 13 inches of twine, and instructions. Get the kit here: DIY Envelope Kit They come in a pack of 2 or 10.
STEP ONE: Fold the envelope and mark where you want the circular tags to go. (I lay the circles on the envelope to see where I like them & put a dot of ink through the center.)
STEP TWO: Unfold the envelope and poke holes through the marks you just made.
STEP THREE: Put the brads through the circles and then through the holes to attach the circular tags.
STEP FOUR: With the circles facing up, run a line of glue or double sided tape across the folded side tab.
STEP FIVE: Pick up the envelope by the glued tab, fold the tab in, and fold the envelope closed, using the glue to seal the side of the envelope. (The fingers show where the glued tab is.)
STEP SIX: Glue or tape the bottom tab and fold it up seal the bottom of the envelope.
STEP SEVEN: Tie one end of the string around the top brad (under the circle). Make several knots and then snip off the little extra piece of string, leaving one long string.
You can decorate the envelope, if you want. (The digital papers I used to decorate the envelope are here: Gingham and Gardens Printable ) Then fill it and seal it by wrapping the string in a figure 8 once or twice. Have fun!
