Supplies needed:
PVA glue. This is a bookmaker's glue and can be found at most art supply stores. Elmer's will work as well.
Newspaper. For the example bags above, I used a Japanese paper that measured (when folded) 11 1/2" wide and 15" tall, and the comics of my regular paper, which were folded and cut down to 11" by 11".
A hole punch and a grommet setter or a Clikit tool. I found my Clikit tool at a discount store. If you google "Clikit" there are several entries.
Grommets
Ribbon or string
Here's how they're made. For this example, I used the Japanese paper:
1. Take the folded paper and fold the already folded side down about 1".
5. Now we'll make gussets on the narrow sides of the bag. Determine how wide you want your gussets to be. They can be as wide or as narrow as you wish. Once you determine how wide you want them to be, fold the bag flat again and crease the second side of your gusset. (The gusset will be the area between your folds.) When you open your bag up, it should be box-like.
6. Bring both edges of each gusset together and crease so the bag will be able to fold flat.
Once you have done this step, your bag should look like this:
7. Measure how wide your gusset is, and fold the BOTTOM of the bag up that same measurement. Remember, the bottom is the side that is NOT folded. On the bag shown, the gusset is 2" wide, so I have folded the bottom up 2". After you fold it once, turn the bag over and fold it up the other side as well so you get a good crease there.
8. Now you're going to create the bottom of your bag. Fold both of the gussets in as if you were wrapping a box. Use your previously made fold lines as guidelines.
11. After your grommets are set, thread a coordinating ribbon through and tie knots on each end. String, yarn, or raffia would work as well. Done! Now you have a cute little gift bag.
