My mom wasn't have a great day so I made her this to cheer her up. :) I had seen something like this on pinterest.com so I made up my own steps to whip this up.
Gather your materials.
Write something on the clothespin. You can choose to put "You have a message..." on it like I did, or just come up with something else (such as "YOU'VE GOT MAIL!").
Cut out a rectangle that fits on the jaws of the clothespin like in the picture. It will be the envelope.
Decorate your envelope however you like.
Cut the envelope in half.
Glue the top half to the top jaw and the bottom half to the bottom jaw.
Get your paper out and cut out a trapezoid that looks like the one in the picture. It should fit inside the jaws when you open the jaws as wide as possible.
(picture of how the trapezoid should be able to fit) By the way, can anyone guess what the book in the background is? (hint: comic of a Studio Ghibli movie)
Put that trapezoid on your paper and draw a rectangle around it like in the picture. (Black lines outline the rectangle, and the black lines inside show the outline of the trapezoid.) Using a pencil, lightly trace around the trapezoid in the rectangle.
Cut out the rectangle, and you should have something like this. The black lines show where you should have penciled in the outline of the trapezoid.
Write your message on the rectangle, making sure that the message is inside the borders of the trapezoid. Also make sure that the trapezoid looks like it is "pointing" to the right. Then fold the rectangle in half so that the words are on the outside, not inside the fold.
You should be able to see the pencil line of the trapezoid. Fold the paper along that line so that you get a "flap" (the pink part of the picture). Flip the paper over and repeat on the other side with the other trapezoid line.
Put glue on both of your flaps (the pink of the picture of step 12) and place the paper sandwich on the bottom jaw of your clothespin. Gently close the jaws, and then open them back up to make sure that your message is facing the right way and isn't upside down. Fix the message if it is.
Then close the jaws, squeeze them together, and wait a bit for the glue to set. Then you're done! I hope you liked my tutorial, and have fun with this. ;)
