Start with a 8 1/2" x 11" sheet of card stock or paper. This works great with pp paper that has Dalmatian spots all over it. I even used camouflage pp for my friend in the military. Fold top right corner to left side of paper to form a triangle like shown.
The paper is doubled and forms a make shift mouth/ pouch. You can fill this with small items such as candy, confetti, stickers etc. I used silly bands.
A 6" x 9" envelope works for mailing. The back can be decorated also. I usually write a message there. This project works great not only for kids to receive, but also for kids to make. I have also sent this origami dog to my adult dog lover friends with a tea bag or some other little trinket.
Thanks for looking and all the comments of encouragement.
