How to Starch Bags Quickly and Easily : Papier Mache Method

I have been selling bath bundles in my little shop on Etsy, and I for those, I’ve been starching the bags that the bundles arrive in. This makes the brown paper bags way more durable–they keep their shape that I’ve folded them into, and they don’t rip easily. This way my customer is able to use them over and over again as a little trinket basket.

If you would like to make the starch mix to form papers bags like this, or even to make a different creative shape with your paper mache, then here’s a great recipe!

What you will need:

3 cups of water (to boil on stove)

1 cup of cool water to mix.

1 cup of corn starch

whisk or fork

(A container to keep any extra in–must be refrigerated to prevent molding)


Step 1

Step 1:

Start getting those 3 cups of water boiling! They can be busy working while you get the mix set up. 😉

Step 2
Step 2:

Combine the 1 cup of cool water and the cup of corn starch. It will be very clumpy, and pretty hard to mix at first. Keep stirring for about a minute. There will still be clumps, but try to mix it around together as evenly as you can.

Step 3:
Step 3

When the water boils, add the corn starch/water mix to the boiling water. This should loosen any of the clumping areas and turn it into a milky-looking water. Remove from heat. Keep stirring until there are no more lumps of starch in the liquid. Let the liquid cool.

Step 4:

Dip your paper/paper bag quickly into the mix. It does not need to be fully soaked to hold its shape. I found that just getting the bag damp was enough for it to keep its shape.

Enjoy your craft!! 🙂
